Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503266, here are decompositions:

7 + 31503259 = 31503266
37 + 31503229 = 31503266
127 + 31503139 = 31503266
163 + 31503103 = 31503266
307 + 31502959 = 31503266
313 + 31502953 = 31503266
409 + 31502857 = 31503266
523 + 31502743 = 31503266

Showing the first eight; more decompositions exist.
