Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506290, here are decompositions:

89 + 506201 = 506290
107 + 506183 = 506290
311 + 505979 = 506290
383 + 505907 = 506290
419 + 505871 = 506290
467 + 505823 = 506290
479 + 505811 = 506290
509 + 505781 = 506290

Showing the first eight; more decompositions exist.
