Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979520, here are decompositions:

97 + 979423 = 979520
151 + 979369 = 979520
193 + 979327 = 979520
229 + 979291 = 979520
313 + 979207 = 979520
331 + 979189 = 979520
349 + 979171 = 979520
457 + 979063 = 979520

Showing the first eight; more decompositions exist.
