Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510362, here are decompositions:

41 + 31510321 = 31510362
43 + 31510319 = 31510362
53 + 31510309 = 31510362
139 + 31510223 = 31510362
193 + 31510169 = 31510362
223 + 31510139 = 31510362
229 + 31510133 = 31510362
241 + 31510121 = 31510362

Showing the first eight; more decompositions exist.
