Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470048, here are decompositions:

11 + 31470037 = 31470048
59 + 31469989 = 31470048
61 + 31469987 = 31470048
191 + 31469857 = 31470048
199 + 31469849 = 31470048
251 + 31469797 = 31470048
307 + 31469741 = 31470048
317 + 31469731 = 31470048

Showing the first eight; more decompositions exist.
