Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503590, here are decompositions:

31 + 31503559 = 31503590
37 + 31503553 = 31503590
61 + 31503529 = 31503590
211 + 31503379 = 31503590
229 + 31503361 = 31503590
277 + 31503313 = 31503590
331 + 31503259 = 31503590
373 + 31503217 = 31503590

Showing the first eight; more decompositions exist.
