Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977448, here are decompositions:

11 + 977437 = 977448
37 + 977411 = 977448
41 + 977407 = 977448
79 + 977369 = 977448
89 + 977359 = 977448
97 + 977351 = 977448
149 + 977299 = 977448
179 + 977269 = 977448

Showing the first eight; more decompositions exist.
