Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494248, here are decompositions:

  • 7 + 31494241 = 31494248
  • 151 + 31494097 = 31494248
  • 157 + 31494091 = 31494248
  • 307 + 31493941 = 31494248
  • 349 + 31493899 = 31494248
  • 367 + 31493881 = 31494248
  • 397 + 31493851 = 31494248
  • 571 + 31493677 = 31494248

Showing the first eight; more decompositions exist.
