Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747792, here are decompositions:

3 + 8747789 = 8747792
103 + 8747689 = 8747792
139 + 8747653 = 8747792
373 + 8747419 = 8747792
463 + 8747329 = 8747792
541 + 8747251 = 8747792
601 + 8747191 = 8747792
673 + 8747119 = 8747792

Showing the first eight; more decompositions exist.
