Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477222, here are decompositions:

41 + 31477181 = 31477222
59 + 31477163 = 31477222
263 + 31476959 = 31477222
401 + 31476821 = 31477222
479 + 31476743 = 31477222
599 + 31476623 = 31477222
761 + 31476461 = 31477222
773 + 31476449 = 31477222

Showing the first eight; more decompositions exist.
