Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526112, here are decompositions:

  • 29 + 31526083 = 31526112
  • 43 + 31526069 = 31526112
  • 61 + 31526051 = 31526112
  • 131 + 31525981 = 31526112
  • 193 + 31525919 = 31526112
  • 199 + 31525913 = 31526112
  • 223 + 31525889 = 31526112
  • 263 + 31525849 = 31526112

Showing the first eight; more decompositions exist.
