Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722940, here are decompositions:

151 + 8722789 = 8722940
229 + 8722711 = 8722940
337 + 8722603 = 8722940
463 + 8722477 = 8722940
547 + 8722393 = 8722940
601 + 8722339 = 8722940
607 + 8722333 = 8722940
643 + 8722297 = 8722940

Showing the first eight; more decompositions exist.
