Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604002, here are decompositions:

11 + 31603991 = 31604002
71 + 31603931 = 31604002
83 + 31603919 = 31604002
113 + 31603889 = 31604002
173 + 31603829 = 31604002
251 + 31603751 = 31604002
263 + 31603739 = 31604002
281 + 31603721 = 31604002

Showing the first eight; more decompositions exist.
