Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620742, here are decompositions:

3 + 8620739 = 8620742
19 + 8620723 = 8620742
79 + 8620663 = 8620742
103 + 8620639 = 8620742
139 + 8620603 = 8620742
199 + 8620543 = 8620742
313 + 8620429 = 8620742
349 + 8620393 = 8620742

Showing the first eight; more decompositions exist.
