Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740156, here are decompositions:

17 + 8740139 = 8740156
59 + 8740097 = 8740156
239 + 8739917 = 8740156
353 + 8739803 = 8740156
389 + 8739767 = 8740156
443 + 8739713 = 8740156
653 + 8739503 = 8740156
797 + 8739359 = 8740156

Showing the first eight; more decompositions exist.
