Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503004, here are decompositions:

11 + 31502993 = 31503004
41 + 31502963 = 31503004
107 + 31502897 = 31503004
227 + 31502777 = 31503004
317 + 31502687 = 31503004
443 + 31502561 = 31503004
521 + 31502483 = 31503004
563 + 31502441 = 31503004

Showing the first eight; more decompositions exist.
