Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503364, here are decompositions:

3 + 31503361 = 31503364
23 + 31503341 = 31503364
41 + 31503323 = 31503364
197 + 31503167 = 31503364
257 + 31503107 = 31503364
311 + 31503053 = 31503364
401 + 31502963 = 31503364
467 + 31502897 = 31503364

Showing the first eight; more decompositions exist.
