Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745192, here are decompositions:

23 + 8745169 = 8745192
31 + 8745161 = 8745192
59 + 8745133 = 8745192
73 + 8745119 = 8745192
173 + 8745019 = 8745192
223 + 8744969 = 8745192
241 + 8744951 = 8745192
251 + 8744941 = 8745192

Showing the first eight; more decompositions exist.
