Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747798, here are decompositions:

61 + 8747737 = 8747798
97 + 8747701 = 8747798
109 + 8747689 = 8747798
181 + 8747617 = 8747798
271 + 8747527 = 8747798
379 + 8747419 = 8747798
541 + 8747257 = 8747798
547 + 8747251 = 8747798

Showing the first eight; more decompositions exist.
