Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977428, here are decompositions:

17 + 977411 = 977428
59 + 977369 = 977428
71 + 977357 = 977428
281 + 977147 = 977428
359 + 977069 = 977428
509 + 976919 = 977428
701 + 976727 = 977428
719 + 976709 = 977428

Showing the first eight; more decompositions exist.
