Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8695990, here are decompositions:

29 + 8695961 = 8695990
41 + 8695949 = 8695990
53 + 8695937 = 8695990
59 + 8695931 = 8695990
101 + 8695889 = 8695990
131 + 8695859 = 8695990
263 + 8695727 = 8695990
389 + 8695601 = 8695990

Showing the first eight; more decompositions exist.
