Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742860, here are decompositions:

3 + 8742857 = 8742860
13 + 8742847 = 8742860
43 + 8742817 = 8742860
73 + 8742787 = 8742860
223 + 8742637 = 8742860
283 + 8742577 = 8742860
331 + 8742529 = 8742860
349 + 8742511 = 8742860

Showing the first eight; more decompositions exist.
