Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503586, here are decompositions:

17 + 31503569 = 31503586
29 + 31503557 = 31503586
263 + 31503323 = 31503586
383 + 31503203 = 31503586
419 + 31503167 = 31503586
467 + 31503119 = 31503586
479 + 31503107 = 31503586
593 + 31502993 = 31503586

Showing the first eight; more decompositions exist.
