Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758480, here are decompositions:

23 + 8758457 = 8758480
47 + 8758433 = 8758480
53 + 8758427 = 8758480
89 + 8758391 = 8758480
167 + 8758313 = 8758480
191 + 8758289 = 8758480
251 + 8758229 = 8758480
281 + 8758199 = 8758480

Showing the first eight; more decompositions exist.
