Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690478, here are decompositions:

67 + 8690411 = 8690478
79 + 8690399 = 8690478
101 + 8690377 = 8690478
107 + 8690371 = 8690478
127 + 8690351 = 8690478
211 + 8690267 = 8690478
257 + 8690221 = 8690478
359 + 8690119 = 8690478

Showing the first eight; more decompositions exist.
