Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444766, here are decompositions:

7 + 31444759 = 31444766
43 + 31444723 = 31444766
139 + 31444627 = 31444766
193 + 31444573 = 31444766
229 + 31444537 = 31444766
277 + 31444489 = 31444766
313 + 31444453 = 31444766
439 + 31444327 = 31444766

Showing the first eight; more decompositions exist.
