Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487576, here are decompositions:

37 + 31487539 = 31487576
103 + 31487473 = 31487576
157 + 31487419 = 31487576
229 + 31487347 = 31487576
313 + 31487263 = 31487576
433 + 31487143 = 31487576
577 + 31486999 = 31487576
853 + 31486723 = 31487576

Showing the first eight; more decompositions exist.
