Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137942, here are decompositions:

  • 31 + 137911 = 137942
  • 73 + 137869 = 137942
  • 139 + 137803 = 137942
  • 151 + 137791 = 137942
  • 199 + 137743 = 137942
  • 229 + 137713 = 137942
  • 283 + 137659 = 137942
  • 349 + 137593 = 137942

Showing the first eight; more decompositions exist.
