Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604994, here are decompositions:

7 + 31604987 = 31604994
61 + 31604933 = 31604994
131 + 31604863 = 31604994
191 + 31604803 = 31604994
227 + 31604767 = 31604994
251 + 31604743 = 31604994
263 + 31604731 = 31604994
271 + 31604723 = 31604994

Showing the first eight; more decompositions exist.
