Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502390, here are decompositions:

89 + 502301 = 502390
113 + 502277 = 502390
131 + 502259 = 502390
173 + 502217 = 502390
257 + 502133 = 502390
269 + 502121 = 502390
311 + 502079 = 502390
347 + 502043 = 502390

Showing the first eight; more decompositions exist.
