Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604060, here are decompositions:

3 + 31604057 = 31604060
73 + 31603987 = 31604060
127 + 31603933 = 31604060
181 + 31603879 = 31604060
349 + 31603711 = 31604060
379 + 31603681 = 31604060
541 + 31603519 = 31604060
571 + 31603489 = 31604060

Showing the first eight; more decompositions exist.
