Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620090, here are decompositions:

41 + 8620049 = 8620090
47 + 8620043 = 8620090
197 + 8619893 = 8620090
233 + 8619857 = 8620090
293 + 8619797 = 8620090
317 + 8619773 = 8620090
467 + 8619623 = 8620090
503 + 8619587 = 8620090

Showing the first eight; more decompositions exist.
