Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503338, here are decompositions:

7 + 31503331 = 31503338
79 + 31503259 = 31503338
109 + 31503229 = 31503338
157 + 31503181 = 31503338
199 + 31503139 = 31503338
277 + 31503061 = 31503338
379 + 31502959 = 31503338
397 + 31502941 = 31503338

Showing the first eight; more decompositions exist.
