Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484822, here are decompositions:

373 + 31484449 = 31484822
409 + 31484413 = 31484822
463 + 31484359 = 31484822
541 + 31484281 = 31484822
613 + 31484209 = 31484822
619 + 31484203 = 31484822
643 + 31484179 = 31484822
661 + 31484161 = 31484822

Showing the first eight; more decompositions exist.
