Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980878, here are decompositions:

47 + 980831 = 980878
149 + 980729 = 980878
167 + 980711 = 980878
191 + 980687 = 980878
257 + 980621 = 980878
389 + 980489 = 980878
419 + 980459 = 980878
461 + 980417 = 980878

Showing the first eight; more decompositions exist.
