Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731494, here are decompositions:

17 + 8731477 = 8731494
47 + 8731447 = 8731494
61 + 8731433 = 8731494
67 + 8731427 = 8731494
113 + 8731381 = 8731494
131 + 8731363 = 8731494
151 + 8731343 = 8731494
173 + 8731321 = 8731494

Showing the first eight; more decompositions exist.
