Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625782, here are decompositions:

73 + 8625709 = 8625782
223 + 8625559 = 8625782
229 + 8625553 = 8625782
241 + 8625541 = 8625782
331 + 8625451 = 8625782
433 + 8625349 = 8625782
439 + 8625343 = 8625782
661 + 8625121 = 8625782

Showing the first eight; more decompositions exist.
