Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660378, here are decompositions:

109 + 8660269 = 8660378
151 + 8660227 = 8660378
157 + 8660221 = 8660378
271 + 8660107 = 8660378
379 + 8659999 = 8660378
421 + 8659957 = 8660378
439 + 8659939 = 8660378
457 + 8659921 = 8660378

Showing the first eight; more decompositions exist.
