Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620424, here are decompositions:

31 + 8620393 = 8620424
97 + 8620327 = 8620424
157 + 8620267 = 8620424
193 + 8620231 = 8620424
283 + 8620141 = 8620424
313 + 8620111 = 8620424
487 + 8619937 = 8620424
541 + 8619883 = 8620424

Showing the first eight; more decompositions exist.
