Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656994, here are decompositions:

61 + 8656933 = 8656994
97 + 8656897 = 8656994
103 + 8656891 = 8656994
163 + 8656831 = 8656994
193 + 8656801 = 8656994
421 + 8656573 = 8656994
433 + 8656561 = 8656994
457 + 8656537 = 8656994

Showing the first eight; more decompositions exist.
