Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502944, here are decompositions:

3 + 31502941 = 31502944
17 + 31502927 = 31502944
47 + 31502897 = 31502944
167 + 31502777 = 31502944
257 + 31502687 = 31502944
383 + 31502561 = 31502944
461 + 31502483 = 31502944
503 + 31502441 = 31502944

Showing the first eight; more decompositions exist.
