Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503390, here are decompositions:

7 + 503383 = 503390
31 + 503359 = 503390
73 + 503317 = 503390
103 + 503287 = 503390
157 + 503233 = 503390
163 + 503227 = 503390
193 + 503197 = 503390
313 + 503077 = 503390

Showing the first eight; more decompositions exist.
