Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546260, here are decompositions:

  • 29 + 31546231 = 31546260
  • 43 + 31546217 = 31546260
  • 61 + 31546199 = 31546260
  • 73 + 31546187 = 31546260
  • 79 + 31546181 = 31546260
  • 101 + 31546159 = 31546260
  • 107 + 31546153 = 31546260
  • 131 + 31546129 = 31546260

Showing the first eight; more decompositions exist.
