Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574922, here are decompositions:

11 + 31574911 = 31574922
31 + 31574891 = 31574922
59 + 31574863 = 31574922
61 + 31574861 = 31574922
73 + 31574849 = 31574922
101 + 31574821 = 31574922
109 + 31574813 = 31574922
149 + 31574773 = 31574922

Showing the first eight; more decompositions exist.
