Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503470, here are decompositions:

109 + 31503361 = 31503470
127 + 31503343 = 31503470
139 + 31503331 = 31503470
157 + 31503313 = 31503470
211 + 31503259 = 31503470
241 + 31503229 = 31503470
331 + 31503139 = 31503470
367 + 31503103 = 31503470

Showing the first eight; more decompositions exist.
