Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531138, here are decompositions:

  • 41 + 33531097 = 33531138
  • 61 + 33531077 = 33531138
  • 79 + 33531059 = 33531138
  • 89 + 33531049 = 33531138
  • 107 + 33531031 = 33531138
  • 127 + 33531011 = 33531138
  • 139 + 33530999 = 33531138
  • 167 + 33530971 = 33531138

Showing the first eight; more decompositions exist.
