Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502738, here are decompositions:

107 + 502631 = 502738
239 + 502499 = 502738
251 + 502487 = 502738
317 + 502421 = 502738
461 + 502277 = 502738
479 + 502259 = 502738
491 + 502247 = 502738
521 + 502217 = 502738

Showing the first eight; more decompositions exist.
