Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748812, here are decompositions:

73 + 8748739 = 8748812
103 + 8748709 = 8748812
139 + 8748673 = 8748812
211 + 8748601 = 8748812
223 + 8748589 = 8748812
229 + 8748583 = 8748812
313 + 8748499 = 8748812
349 + 8748463 = 8748812

Showing the first eight; more decompositions exist.
