Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476242, here are decompositions:

3 + 31476239 = 31476242
73 + 31476169 = 31476242
211 + 31476031 = 31476242
229 + 31476013 = 31476242
313 + 31475929 = 31476242
331 + 31475911 = 31476242
463 + 31475779 = 31476242
619 + 31475623 = 31476242

Showing the first eight; more decompositions exist.
