Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472122, here are decompositions:

  • 53 + 31472069 = 31472122
  • 131 + 31471991 = 31472122
  • 239 + 31471883 = 31472122
  • 359 + 31471763 = 31472122
  • 419 + 31471703 = 31472122
  • 599 + 31471523 = 31472122
  • 641 + 31471481 = 31472122
  • 653 + 31471469 = 31472122

Showing the first eight; more decompositions exist.
