Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510442, here are decompositions:

41 + 510401 = 510442
59 + 510383 = 510442
131 + 510311 = 510442
239 + 510203 = 510442
263 + 510179 = 510442
353 + 510089 = 510442
479 + 509963 = 510442
503 + 509939 = 510442

Showing the first eight; more decompositions exist.
