Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576362, here are decompositions:

11 + 31576351 = 31576362
73 + 31576289 = 31576362
79 + 31576283 = 31576362
101 + 31576261 = 31576362
109 + 31576253 = 31576362
131 + 31576231 = 31576362
151 + 31576211 = 31576362
163 + 31576199 = 31576362

Showing the first eight; more decompositions exist.
