Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731542, here are decompositions:

11 + 8731531 = 8731542
13 + 8731529 = 8731542
31 + 8731511 = 8731542
41 + 8731501 = 8731542
109 + 8731433 = 8731542
173 + 8731369 = 8731542
179 + 8731363 = 8731542
199 + 8731343 = 8731542

Showing the first eight; more decompositions exist.
