Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624094, here are decompositions:

127 + 31623967 = 31624094
163 + 31623931 = 31624094
193 + 31623901 = 31624094
277 + 31623817 = 31624094
373 + 31623721 = 31624094
487 + 31623607 = 31624094
571 + 31623523 = 31624094
613 + 31623481 = 31624094

Showing the first eight; more decompositions exist.
