Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503562, here are decompositions:

3 + 31503559 = 31503562
5 + 31503557 = 31503562
53 + 31503509 = 31503562
239 + 31503323 = 31503562
353 + 31503209 = 31503562
359 + 31503203 = 31503562
383 + 31503179 = 31503562
443 + 31503119 = 31503562

Showing the first eight; more decompositions exist.
