Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731486, here are decompositions:

53 + 8731433 = 8731486
59 + 8731427 = 8731486
173 + 8731313 = 8731486
347 + 8731139 = 8731486
383 + 8731103 = 8731486
389 + 8731097 = 8731486
503 + 8730983 = 8731486
509 + 8730977 = 8731486

Showing the first eight; more decompositions exist.
