Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977442, here are decompositions:

5 + 977437 = 977442
29 + 977413 = 977442
31 + 977411 = 977442
73 + 977369 = 977442
79 + 977363 = 977442
83 + 977359 = 977442
173 + 977269 = 977442
199 + 977243 = 977442

Showing the first eight; more decompositions exist.
