Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620992, here are decompositions:

19 + 8620973 = 8620992
41 + 8620951 = 8620992
43 + 8620949 = 8620992
131 + 8620861 = 8620992
151 + 8620841 = 8620992
269 + 8620723 = 8620992
271 + 8620721 = 8620992
353 + 8620639 = 8620992

Showing the first eight; more decompositions exist.
