Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484832, here are decompositions:

11 + 31484821 = 31484832
31 + 31484801 = 31484832
61 + 31484771 = 31484832
79 + 31484753 = 31484832
263 + 31484569 = 31484832
383 + 31484449 = 31484832
419 + 31484413 = 31484832
479 + 31484353 = 31484832

Showing the first eight; more decompositions exist.
