Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503382, here are decompositions:

3 + 31503379 = 31503382
41 + 31503341 = 31503382
59 + 31503323 = 31503382
173 + 31503209 = 31503382
179 + 31503203 = 31503382
263 + 31503119 = 31503382
389 + 31502993 = 31503382
419 + 31502963 = 31503382

Showing the first eight; more decompositions exist.
