Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484444, here are decompositions:

31 + 31484413 = 31484444
67 + 31484377 = 31484444
127 + 31484317 = 31484444
163 + 31484281 = 31484444
241 + 31484203 = 31484444
283 + 31484161 = 31484444
373 + 31484071 = 31484444
463 + 31483981 = 31484444

Showing the first eight; more decompositions exist.
