Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706782, here are decompositions:

31 + 8706751 = 8706782
229 + 8706553 = 8706782
379 + 8706403 = 8706782
421 + 8706361 = 8706782
433 + 8706349 = 8706782
499 + 8706283 = 8706782
541 + 8706241 = 8706782
613 + 8706169 = 8706782

Showing the first eight; more decompositions exist.
