Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494822, here are decompositions:

5 + 31494817 = 31494822
13 + 31494809 = 31494822
41 + 31494781 = 31494822
53 + 31494769 = 31494822
59 + 31494763 = 31494822
101 + 31494721 = 31494822
109 + 31494713 = 31494822
131 + 31494691 = 31494822

Showing the first eight; more decompositions exist.
