Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620492, here are decompositions:

131 + 8620361 = 8620492
233 + 8620259 = 8620492
281 + 8620211 = 8620492
359 + 8620133 = 8620492
383 + 8620109 = 8620492
443 + 8620049 = 8620492
449 + 8620043 = 8620492
599 + 8619893 = 8620492

Showing the first eight; more decompositions exist.
