Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503758, here are decompositions:

7 + 31503751 = 31503758
31 + 31503727 = 31503758
127 + 31503631 = 31503758
199 + 31503559 = 31503758
229 + 31503529 = 31503758
379 + 31503379 = 31503758
397 + 31503361 = 31503758
421 + 31503337 = 31503758

Showing the first eight; more decompositions exist.
