Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522228, here are decompositions:

47 + 31522181 = 31522228
137 + 31522091 = 31522228
167 + 31522061 = 31522228
251 + 31521977 = 31522228
557 + 31521671 = 31522228
587 + 31521641 = 31522228
719 + 31521509 = 31522228
761 + 31521467 = 31522228

Showing the first eight; more decompositions exist.
