Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646042, here are decompositions:

61 + 8645981 = 8646042
71 + 8645971 = 8646042
101 + 8645941 = 8646042
179 + 8645863 = 8646042
193 + 8645849 = 8646042
239 + 8645803 = 8646042
269 + 8645773 = 8646042
281 + 8645761 = 8646042

Showing the first eight; more decompositions exist.
