Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503814, here are decompositions:

3 + 31503811 = 31503814
5 + 31503809 = 31503814
101 + 31503713 = 31503814
257 + 31503557 = 31503814
491 + 31503323 = 31503814
647 + 31503167 = 31503814
761 + 31503053 = 31503814
821 + 31502993 = 31503814

Showing the first eight; more decompositions exist.
