Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977538, here are decompositions:

17 + 977521 = 977538
31 + 977507 = 977538
101 + 977437 = 977538
127 + 977411 = 977538
131 + 977407 = 977538
179 + 977359 = 977538
181 + 977357 = 977538
239 + 977299 = 977538

Showing the first eight; more decompositions exist.
