Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503336, here are decompositions:

5 + 31503331 = 31503336
13 + 31503323 = 31503336
23 + 31503313 = 31503336
107 + 31503229 = 31503336
127 + 31503209 = 31503336
157 + 31503179 = 31503336
197 + 31503139 = 31503336
229 + 31503107 = 31503336

Showing the first eight; more decompositions exist.
