Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604888, here are decompositions:

157 + 31604731 = 31604888
199 + 31604689 = 31604888
241 + 31604647 = 31604888
277 + 31604611 = 31604888
331 + 31604557 = 31604888
379 + 31604509 = 31604888
541 + 31604347 = 31604888
547 + 31604341 = 31604888

Showing the first eight; more decompositions exist.
