Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470776, here are decompositions:

67 + 31470709 = 31470776
157 + 31470619 = 31470776
229 + 31470547 = 31470776
307 + 31470469 = 31470776
367 + 31470409 = 31470776
397 + 31470379 = 31470776
439 + 31470337 = 31470776
577 + 31470199 = 31470776

Showing the first eight; more decompositions exist.
