Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986890, here are decompositions:

41 + 986849 = 986890
53 + 986837 = 986890
71 + 986819 = 986890
89 + 986801 = 986890
131 + 986759 = 986890
173 + 986717 = 986890
197 + 986693 = 986890
257 + 986633 = 986890

Showing the first eight; more decompositions exist.
