Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484456, here are decompositions:

7 + 31484449 = 31484456
43 + 31484413 = 31484456
79 + 31484377 = 31484456
97 + 31484359 = 31484456
103 + 31484353 = 31484456
139 + 31484317 = 31484456
277 + 31484179 = 31484456
313 + 31484143 = 31484456

Showing the first eight; more decompositions exist.
