Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604382, here are decompositions:

11 + 31604371 = 31604382
23 + 31604359 = 31604382
41 + 31604341 = 31604382
71 + 31604311 = 31604382
79 + 31604303 = 31604382
83 + 31604299 = 31604382
101 + 31604281 = 31604382
163 + 31604219 = 31604382

Showing the first eight; more decompositions exist.
