Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522994, here are decompositions:

7 + 31522987 = 31522994
43 + 31522951 = 31522994
277 + 31522717 = 31522994
331 + 31522663 = 31522994
337 + 31522657 = 31522994
397 + 31522597 = 31522994
631 + 31522363 = 31522994
751 + 31522243 = 31522994

Showing the first eight; more decompositions exist.
