Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503508, here are decompositions:

167 + 31503341 = 31503508
389 + 31503119 = 31503508
401 + 31503107 = 31503508
809 + 31502699 = 31503508
821 + 31502687 = 31503508
947 + 31502561 = 31503508
1019 + 31502489 = 31503508
1049 + 31502459 = 31503508

Showing the first eight; more decompositions exist.
