Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977890, here are decompositions:

29 + 977861 = 977890
41 + 977849 = 977890
59 + 977831 = 977890
71 + 977819 = 977890
167 + 977723 = 977890
197 + 977693 = 977890
281 + 977609 = 977890
383 + 977507 = 977890

Showing the first eight; more decompositions exist.
