Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519362, here are decompositions:

5 + 31519357 = 31519362
41 + 31519321 = 31519362
73 + 31519289 = 31519362
109 + 31519253 = 31519362
151 + 31519211 = 31519362
163 + 31519199 = 31519362
181 + 31519181 = 31519362
211 + 31519151 = 31519362

Showing the first eight; more decompositions exist.
