Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979142, here are decompositions:

79 + 979063 = 979142
211 + 978931 = 979142
271 + 978871 = 979142
499 + 978643 = 979142
523 + 978619 = 979142
601 + 978541 = 979142
631 + 978511 = 979142
739 + 978403 = 979142

Showing the first eight; more decompositions exist.
