Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484472, here are decompositions:

11 + 31484461 = 31484472
23 + 31484449 = 31484472
59 + 31484413 = 31484472
109 + 31484363 = 31484472
113 + 31484359 = 31484472
191 + 31484281 = 31484472
233 + 31484239 = 31484472
263 + 31484209 = 31484472

Showing the first eight; more decompositions exist.
