Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484424, here are decompositions:

7 + 31484417 = 31484424
11 + 31484413 = 31484424
47 + 31484377 = 31484424
61 + 31484363 = 31484424
71 + 31484353 = 31484424
107 + 31484317 = 31484424
157 + 31484267 = 31484424
263 + 31484161 = 31484424

Showing the first eight; more decompositions exist.
