Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604210, here are decompositions:

19 + 31604191 = 31604210
73 + 31604137 = 31604210
223 + 31603987 = 31604210
277 + 31603933 = 31604210
331 + 31603879 = 31604210
367 + 31603843 = 31604210
409 + 31603801 = 31604210
499 + 31603711 = 31604210

Showing the first eight; more decompositions exist.
