Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503674, here are decompositions:

31 + 31503643 = 31503674
43 + 31503631 = 31503674
313 + 31503361 = 31503674
331 + 31503343 = 31503674
337 + 31503337 = 31503674
457 + 31503217 = 31503674
523 + 31503151 = 31503674
571 + 31503103 = 31503674

Showing the first eight; more decompositions exist.
