Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487476, here are decompositions:

3 + 31487473 = 31487476
5 + 31487471 = 31487476
29 + 31487447 = 31487476
107 + 31487369 = 31487476
113 + 31487363 = 31487476
197 + 31487279 = 31487476
389 + 31487087 = 31487476
443 + 31487033 = 31487476

Showing the first eight; more decompositions exist.
