Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537006, here are decompositions:

3 + 31537003 = 31537006
5 + 31537001 = 31537006
23 + 31536983 = 31537006
47 + 31536959 = 31537006
89 + 31536917 = 31537006
233 + 31536773 = 31537006
467 + 31536539 = 31537006
647 + 31536359 = 31537006

Showing the first eight; more decompositions exist.
