Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509236, here are decompositions:

89 + 509147 = 509236
113 + 509123 = 509236
149 + 509087 = 509236
173 + 509063 = 509236
263 + 508973 = 509236
293 + 508943 = 509236
317 + 508919 = 509236
389 + 508847 = 509236

Showing the first eight; more decompositions exist.
