Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552922, here are decompositions:

3 + 31552919 = 31552922
31 + 31552891 = 31552922
43 + 31552879 = 31552922
229 + 31552693 = 31552922
241 + 31552681 = 31552922
283 + 31552639 = 31552922
433 + 31552489 = 31552922
571 + 31552351 = 31552922

Showing the first eight; more decompositions exist.
