Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980618, here are decompositions:

19 + 980599 = 980618
31 + 980587 = 980618
61 + 980557 = 980618
127 + 980491 = 980618
241 + 980377 = 980618
421 + 980197 = 980618
439 + 980179 = 980618
487 + 980131 = 980618

Showing the first eight; more decompositions exist.
