Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497346, here are decompositions:

  • 5 + 31497341 = 31497346
  • 47 + 31497299 = 31497346
  • 53 + 31497293 = 31497346
  • 59 + 31497287 = 31497346
  • 263 + 31497083 = 31497346
  • 383 + 31496963 = 31497346
  • 389 + 31496957 = 31497346
  • 563 + 31496783 = 31497346

Showing the first eight; more decompositions exist.
