Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522982, here are decompositions:

3 + 31522979 = 31522982
31 + 31522951 = 31522982
109 + 31522873 = 31522982
313 + 31522669 = 31522982
349 + 31522633 = 31522982
433 + 31522549 = 31522982
523 + 31522459 = 31522982
541 + 31522441 = 31522982

Showing the first eight; more decompositions exist.
