Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 946720, here are decompositions:

3 + 946717 = 946720
23 + 946697 = 946720
53 + 946667 = 946720
59 + 946661 = 946720
113 + 946607 = 946720
233 + 946487 = 946720
251 + 946469 = 946720
353 + 946367 = 946720

Showing the first eight; more decompositions exist.
