Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522274, here are decompositions:

31 + 31522243 = 31522274
67 + 31522207 = 31522274
283 + 31521991 = 31522274
601 + 31521673 = 31522274
607 + 31521667 = 31522274
631 + 31521643 = 31522274
733 + 31521541 = 31522274
1051 + 31521223 = 31522274

Showing the first eight; more decompositions exist.
