Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540494, here are decompositions:

  • 5 + 31540489 = 31540494
  • 23 + 31540471 = 31540494
  • 53 + 31540441 = 31540494
  • 131 + 31540363 = 31540494
  • 151 + 31540343 = 31540494
  • 197 + 31540297 = 31540494
  • 233 + 31540261 = 31540494
  • 277 + 31540217 = 31540494

Showing the first eight; more decompositions exist.
