Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731816, here are decompositions:

29 + 8731787 = 8731816
53 + 8731763 = 8731816
59 + 8731757 = 8731816
173 + 8731643 = 8731816
179 + 8731637 = 8731816
383 + 8731433 = 8731816
389 + 8731427 = 8731816
503 + 8731313 = 8731816

Showing the first eight; more decompositions exist.
