Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742764, here are decompositions:

127 + 8742637 = 8742764
193 + 8742571 = 8742764
223 + 8742541 = 8742764
271 + 8742493 = 8742764
397 + 8742367 = 8742764
571 + 8742193 = 8742764
577 + 8742187 = 8742764
607 + 8742157 = 8742764

Showing the first eight; more decompositions exist.
