Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747732, here are decompositions:

31 + 8747701 = 8747732
43 + 8747689 = 8747732
79 + 8747653 = 8747732
109 + 8747623 = 8747732
193 + 8747539 = 8747732
313 + 8747419 = 8747732
541 + 8747191 = 8747732
613 + 8747119 = 8747732

Showing the first eight; more decompositions exist.
