Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503116, here are decompositions:

13 + 31503103 = 31503116
157 + 31502959 = 31503116
163 + 31502953 = 31503116
193 + 31502923 = 31503116
373 + 31502743 = 31503116
457 + 31502659 = 31503116
577 + 31502539 = 31503116
787 + 31502329 = 31503116

Showing the first eight; more decompositions exist.
