Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557922, here are decompositions:

3 + 31557919 = 31557922
41 + 31557881 = 31557922
89 + 31557833 = 31557922
113 + 31557809 = 31557922
131 + 31557791 = 31557922
173 + 31557749 = 31557922
191 + 31557731 = 31557922
239 + 31557683 = 31557922

Showing the first eight; more decompositions exist.
