Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503708, here are decompositions:

139 + 31503569 = 31503708
149 + 31503559 = 31503708
151 + 31503557 = 31503708
179 + 31503529 = 31503708
199 + 31503509 = 31503708
239 + 31503469 = 31503708
347 + 31503361 = 31503708
367 + 31503341 = 31503708

Showing the first eight; more decompositions exist.
