Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604554, here are decompositions:

53 + 31604501 = 31604554
101 + 31604453 = 31604554
167 + 31604387 = 31604554
197 + 31604357 = 31604554
251 + 31604303 = 31604554
257 + 31604297 = 31604554
503 + 31604051 = 31604554
521 + 31604033 = 31604554

Showing the first eight; more decompositions exist.
