Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476042, here are decompositions:

11 + 31476031 = 31476042
29 + 31476013 = 31476042
79 + 31475963 = 31476042
89 + 31475953 = 31476042
113 + 31475929 = 31476042
131 + 31475911 = 31476042
193 + 31475849 = 31476042
229 + 31475813 = 31476042

Showing the first eight; more decompositions exist.
