Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537544, here are decompositions:

37 + 31537507 = 31537544
67 + 31537477 = 31537544
271 + 31537273 = 31537544
277 + 31537267 = 31537544
397 + 31537147 = 31537544
457 + 31537087 = 31537544
541 + 31537003 = 31537544
601 + 31536943 = 31537544

Showing the first eight; more decompositions exist.
