Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604030, here are decompositions:

43 + 31603987 = 31604030
97 + 31603933 = 31604030
151 + 31603879 = 31604030
229 + 31603801 = 31604030
313 + 31603717 = 31604030
349 + 31603681 = 31604030
373 + 31603657 = 31604030
421 + 31603609 = 31604030

Showing the first eight; more decompositions exist.
