Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503044, here are decompositions:

103 + 31502941 = 31503044
163 + 31502881 = 31503044
283 + 31502761 = 31503044
457 + 31502587 = 31503044
487 + 31502557 = 31503044
613 + 31502431 = 31503044
673 + 31502371 = 31503044
691 + 31502353 = 31503044

Showing the first eight; more decompositions exist.
