Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980890, here are decompositions:

3 + 980887 = 980890
59 + 980831 = 980890
89 + 980801 = 980890
173 + 980717 = 980890
179 + 980711 = 980890
269 + 980621 = 980890
311 + 980579 = 980890
401 + 980489 = 980890

Showing the first eight; more decompositions exist.
