Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604480, here are decompositions:

97 + 31604383 = 31604480
109 + 31604371 = 31604480
139 + 31604341 = 31604480
181 + 31604299 = 31604480
199 + 31604281 = 31604480
547 + 31603933 = 31604480
601 + 31603879 = 31604480
769 + 31603711 = 31604480

Showing the first eight; more decompositions exist.
