Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522552, here are decompositions:

3 + 31522549 = 31522552
11 + 31522541 = 31522552
23 + 31522529 = 31522552
29 + 31522523 = 31522552
59 + 31522493 = 31522552
101 + 31522451 = 31522552
179 + 31522373 = 31522552
239 + 31522313 = 31522552

Showing the first eight; more decompositions exist.
