Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623734, here are decompositions:

3 + 31623731 = 31623734
13 + 31623721 = 31623734
31 + 31623703 = 31623734
67 + 31623667 = 31623734
127 + 31623607 = 31623734
211 + 31623523 = 31623734
223 + 31623511 = 31623734
313 + 31623421 = 31623734

Showing the first eight; more decompositions exist.
