Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476090, here are decompositions:

17 + 31476073 = 31476090
31 + 31476059 = 31476090
59 + 31476031 = 31476090
73 + 31476017 = 31476090
127 + 31475963 = 31476090
137 + 31475953 = 31476090
179 + 31475911 = 31476090
181 + 31475909 = 31476090

Showing the first eight; more decompositions exist.
