Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482944, here are decompositions:

37 + 31482907 = 31482944
277 + 31482667 = 31482944
313 + 31482631 = 31482944
331 + 31482613 = 31482944
433 + 31482511 = 31482944
601 + 31482343 = 31482944
607 + 31482337 = 31482944
673 + 31482271 = 31482944

Showing the first eight; more decompositions exist.
