Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979978, here are decompositions:

29 + 979949 = 979978
59 + 979919 = 979978
71 + 979907 = 979978
89 + 979889 = 979978
191 + 979787 = 979978
269 + 979709 = 979978
449 + 979529 = 979978
521 + 979457 = 979978

Showing the first eight; more decompositions exist.
