Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503158, here are decompositions:

11 + 503147 = 503158
197 + 502961 = 503158
239 + 502919 = 503158
311 + 502847 = 503158
317 + 502841 = 503158
389 + 502769 = 503158
641 + 502517 = 503158
659 + 502499 = 503158

Showing the first eight; more decompositions exist.
