Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623746, here are decompositions:

43 + 31623703 = 31623746
79 + 31623667 = 31623746
139 + 31623607 = 31623746
157 + 31623589 = 31623746
223 + 31623523 = 31623746
307 + 31623439 = 31623746
373 + 31623373 = 31623746
409 + 31623337 = 31623746

Showing the first eight; more decompositions exist.
