Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61220, here are decompositions:

  • 67 + 61153 = 61220
  • 79 + 61141 = 61220
  • 163 + 61057 = 61220
  • 193 + 61027 = 61220
  • 277 + 60943 = 61220
  • 283 + 60937 = 61220
  • 307 + 60913 = 61220
  • 331 + 60889 = 61220

Showing the first eight; more decompositions exist.
