Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484450, here are decompositions:

37 + 31484413 = 31484450
73 + 31484377 = 31484450
97 + 31484353 = 31484450
211 + 31484239 = 31484450
241 + 31484209 = 31484450
271 + 31484179 = 31484450
307 + 31484143 = 31484450
379 + 31484071 = 31484450

Showing the first eight; more decompositions exist.
