Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470746, here are decompositions:

37 + 31470709 = 31470746
127 + 31470619 = 31470746
199 + 31470547 = 31470746
277 + 31470469 = 31470746
337 + 31470409 = 31470746
367 + 31470379 = 31470746
409 + 31470337 = 31470746
487 + 31470259 = 31470746

Showing the first eight; more decompositions exist.
