Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546212, here are decompositions:

  • 13 + 31546199 = 31546212
  • 31 + 31546181 = 31546212
  • 53 + 31546159 = 31546212
  • 59 + 31546153 = 31546212
  • 83 + 31546129 = 31546212
  • 101 + 31546111 = 31546212
  • 149 + 31546063 = 31546212
  • 193 + 31546019 = 31546212

Showing the first eight; more decompositions exist.
