Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623776, here are decompositions:

73 + 31623703 = 31623776
109 + 31623667 = 31623776
277 + 31623499 = 31623776
337 + 31623439 = 31623776
433 + 31623343 = 31623776
439 + 31623337 = 31623776
577 + 31623199 = 31623776
607 + 31623169 = 31623776

Showing the first eight; more decompositions exist.
