Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503514, here are decompositions:

5 + 31503509 = 31503514
71 + 31503443 = 31503514
173 + 31503341 = 31503514
191 + 31503323 = 31503514
311 + 31503203 = 31503514
347 + 31503167 = 31503514
461 + 31503053 = 31503514
521 + 31502993 = 31503514

Showing the first eight; more decompositions exist.
