Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977558, here are decompositions:

19 + 977539 = 977558
37 + 977521 = 977558
151 + 977407 = 977558
199 + 977359 = 977558
349 + 977209 = 977558
367 + 977191 = 977558
409 + 977149 = 977558
601 + 976957 = 977558

Showing the first eight; more decompositions exist.
