Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604442, here are decompositions:

59 + 31604383 = 31604442
71 + 31604371 = 31604442
83 + 31604359 = 31604442
101 + 31604341 = 31604442
131 + 31604311 = 31604442
139 + 31604303 = 31604442
179 + 31604263 = 31604442
223 + 31604219 = 31604442

Showing the first eight; more decompositions exist.
