Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484496, here are decompositions:

47 + 31484449 = 31484496
79 + 31484417 = 31484496
83 + 31484413 = 31484496
137 + 31484359 = 31484496
157 + 31484339 = 31484496
179 + 31484317 = 31484496
193 + 31484303 = 31484496
229 + 31484267 = 31484496

Showing the first eight; more decompositions exist.
