Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604924, here are decompositions:

61 + 31604863 = 31604924
157 + 31604767 = 31604924
181 + 31604743 = 31604924
193 + 31604731 = 31604924
277 + 31604647 = 31604924
283 + 31604641 = 31604924
313 + 31604611 = 31604924
367 + 31604557 = 31604924

Showing the first eight; more decompositions exist.
