Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977578, here are decompositions:

11 + 977567 = 977578
71 + 977507 = 977578
131 + 977447 = 977578
167 + 977411 = 977578
227 + 977351 = 977578
431 + 977147 = 977578
491 + 977087 = 977578
509 + 977069 = 977578

Showing the first eight; more decompositions exist.
