Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742932, here are decompositions:

13 + 8742919 = 8742932
193 + 8742739 = 8742932
421 + 8742511 = 8742932
433 + 8742499 = 8742932
439 + 8742493 = 8742932
463 + 8742469 = 8742932
619 + 8742313 = 8742932
673 + 8742259 = 8742932

Showing the first eight; more decompositions exist.
