Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712782, here are decompositions:

3 + 8712779 = 8712782
31 + 8712751 = 8712782
73 + 8712709 = 8712782
181 + 8712601 = 8712782
409 + 8712373 = 8712782
433 + 8712349 = 8712782
523 + 8712259 = 8712782
601 + 8712181 = 8712782

Showing the first eight; more decompositions exist.
