Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747550, here are decompositions:

11 + 8747539 = 8747550
23 + 8747527 = 8747550
37 + 8747513 = 8747550
61 + 8747489 = 8747550
67 + 8747483 = 8747550
79 + 8747471 = 8747550
109 + 8747441 = 8747550
127 + 8747423 = 8747550

Showing the first eight; more decompositions exist.
