Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503502, here are decompositions:

59 + 31503443 = 31503502
179 + 31503323 = 31503502
293 + 31503209 = 31503502
383 + 31503119 = 31503502
449 + 31503053 = 31503502
509 + 31502993 = 31503502
941 + 31502561 = 31503502
1013 + 31502489 = 31503502

Showing the first eight; more decompositions exist.
