Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979840, here are decompositions:

53 + 979787 = 979840
83 + 979757 = 979840
131 + 979709 = 979840
149 + 979691 = 979840
311 + 979529 = 979840
359 + 979481 = 979840
383 + 979457 = 979840
401 + 979439 = 979840

Showing the first eight; more decompositions exist.
