Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494544, here are decompositions:

41 + 31494503 = 31494544
47 + 31494497 = 31494544
101 + 31494443 = 31494544
113 + 31494431 = 31494544
197 + 31494347 = 31494544
251 + 31494293 = 31494544
281 + 31494263 = 31494544
383 + 31494161 = 31494544

Showing the first eight; more decompositions exist.
