Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620432, here are decompositions:

3 + 8620429 = 8620432
71 + 8620361 = 8620432
83 + 8620349 = 8620432
173 + 8620259 = 8620432
281 + 8620151 = 8620432
311 + 8620121 = 8620432
383 + 8620049 = 8620432
389 + 8620043 = 8620432

Showing the first eight; more decompositions exist.
