Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522600, here are decompositions:

3 + 31522597 = 31522600
17 + 31522583 = 31522600
47 + 31522553 = 31522600
59 + 31522541 = 31522600
71 + 31522529 = 31522600
107 + 31522493 = 31522600
149 + 31522451 = 31522600
167 + 31522433 = 31522600

Showing the first eight; more decompositions exist.
