Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748818, here are decompositions:

7 + 8748811 = 8748818
31 + 8748787 = 8748818
79 + 8748739 = 8748818
109 + 8748709 = 8748818
229 + 8748589 = 8748818
349 + 8748469 = 8748818
457 + 8748361 = 8748818
487 + 8748331 = 8748818

Showing the first eight; more decompositions exist.
