Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604412, here are decompositions:

29 + 31604383 = 31604412
41 + 31604371 = 31604412
53 + 31604359 = 31604412
71 + 31604341 = 31604412
101 + 31604311 = 31604412
109 + 31604303 = 31604412
113 + 31604299 = 31604412
131 + 31604281 = 31604412

Showing the first eight; more decompositions exist.
