Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977580, here are decompositions:

13 + 977567 = 977580
41 + 977539 = 977580
59 + 977521 = 977580
67 + 977513 = 977580
73 + 977507 = 977580
167 + 977413 = 977580
173 + 977407 = 977580
211 + 977369 = 977580

Showing the first eight; more decompositions exist.
