Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522724, here are decompositions:

7 + 31522717 = 31522724
31 + 31522693 = 31522724
61 + 31522663 = 31522724
67 + 31522657 = 31522724
127 + 31522597 = 31522724
283 + 31522441 = 31522724
313 + 31522411 = 31522724
367 + 31522357 = 31522724

Showing the first eight; more decompositions exist.
