Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623764, here are decompositions:

43 + 31623721 = 31623764
61 + 31623703 = 31623764
97 + 31623667 = 31623764
157 + 31623607 = 31623764
241 + 31623523 = 31623764
283 + 31623481 = 31623764
421 + 31623343 = 31623764
541 + 31623223 = 31623764

Showing the first eight; more decompositions exist.
