Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727042, here are decompositions:

11 + 8727031 = 8727042
53 + 8726989 = 8727042
59 + 8726983 = 8727042
73 + 8726969 = 8727042
89 + 8726953 = 8727042
179 + 8726863 = 8727042
193 + 8726849 = 8727042
239 + 8726803 = 8727042

Showing the first eight; more decompositions exist.
