Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624064, here are decompositions:

61 + 31624003 = 31624064
97 + 31623967 = 31624064
163 + 31623901 = 31624064
397 + 31623667 = 31624064
457 + 31623607 = 31624064
541 + 31623523 = 31624064
643 + 31623421 = 31624064
691 + 31623373 = 31624064

Showing the first eight; more decompositions exist.
