Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503582, here are decompositions:

13 + 31503569 = 31503582
23 + 31503559 = 31503582
29 + 31503553 = 31503582
53 + 31503529 = 31503582
73 + 31503509 = 31503582
113 + 31503469 = 31503582
139 + 31503443 = 31503582
239 + 31503343 = 31503582

Showing the first eight; more decompositions exist.
