Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522910, here are decompositions:

37 + 31522873 = 31522910
163 + 31522747 = 31522910
193 + 31522717 = 31522910
241 + 31522669 = 31522910
277 + 31522633 = 31522910
313 + 31522597 = 31522910
499 + 31522411 = 31522910
547 + 31522363 = 31522910

Showing the first eight; more decompositions exist.
