Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470092, here are decompositions:

19 + 31470073 = 31470092
79 + 31470013 = 31470092
103 + 31469989 = 31470092
139 + 31469953 = 31470092
331 + 31469761 = 31470092
421 + 31469671 = 31470092
439 + 31469653 = 31470092
463 + 31469629 = 31470092

Showing the first eight; more decompositions exist.
