Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742718, here are decompositions:

29 + 8742689 = 8742718
41 + 8742677 = 8742718
167 + 8742551 = 8742718
269 + 8742449 = 8742718
317 + 8742401 = 8742718
359 + 8742359 = 8742718
401 + 8742317 = 8742718
521 + 8742197 = 8742718

Showing the first eight; more decompositions exist.
