Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615346, here are decompositions:

  • 3 + 31615343 = 31615346
  • 13 + 31615333 = 31615346
  • 73 + 31615273 = 31615346
  • 109 + 31615237 = 31615346
  • 193 + 31615153 = 31615346
  • 283 + 31615063 = 31615346
  • 307 + 31615039 = 31615346
  • 457 + 31614889 = 31615346

Showing the first eight; more decompositions exist.
