Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463444, here are decompositions:

37 + 31463407 = 31463444
127 + 31463317 = 31463444
163 + 31463281 = 31463444
241 + 31463203 = 31463444
277 + 31463167 = 31463444
283 + 31463161 = 31463444
307 + 31463137 = 31463444
367 + 31463077 = 31463444

Showing the first eight; more decompositions exist.
