Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604934, here are decompositions:

71 + 31604863 = 31604934
131 + 31604803 = 31604934
167 + 31604767 = 31604934
191 + 31604743 = 31604934
211 + 31604723 = 31604934
293 + 31604641 = 31604934
307 + 31604627 = 31604934
331 + 31604603 = 31604934

Showing the first eight; more decompositions exist.
