Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294989380, here are decompositions:

  • 67 + 4294989313 = 4294989380
  • 139 + 4294989241 = 4294989380
  • 211 + 4294989169 = 4294989380
  • 229 + 4294989151 = 4294989380
  • 277 + 4294989103 = 4294989380
  • 307 + 4294989073 = 4294989380
  • 397 + 4294988983 = 4294989380
  • 433 + 4294988947 = 4294989380

Showing the first eight; more decompositions exist.
