Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977430, here are decompositions:

17 + 977413 = 977430
19 + 977411 = 977430
23 + 977407 = 977430
61 + 977369 = 977430
67 + 977363 = 977430
71 + 977359 = 977430
73 + 977357 = 977430
79 + 977351 = 977430

Showing the first eight; more decompositions exist.
