Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522902, here are decompositions:

13 + 31522889 = 31522902
29 + 31522873 = 31522902
79 + 31522823 = 31522902
233 + 31522669 = 31522902
239 + 31522663 = 31522902
269 + 31522633 = 31522902
311 + 31522591 = 31522902
349 + 31522553 = 31522902

Showing the first eight; more decompositions exist.
