Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980642, here are decompositions:

43 + 980599 = 980642
139 + 980503 = 980642
151 + 980491 = 980642
193 + 980449 = 980642
211 + 980431 = 980642
241 + 980401 = 980642
349 + 980293 = 980642
463 + 980179 = 980642

Showing the first eight; more decompositions exist.
