Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470044, here are decompositions:

7 + 31470037 = 31470044
31 + 31470013 = 31470044
283 + 31469761 = 31470044
313 + 31469731 = 31470044
373 + 31469671 = 31470044
421 + 31469623 = 31470044
457 + 31469587 = 31470044
577 + 31469467 = 31470044

Showing the first eight; more decompositions exist.
