Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758420, here are decompositions:

29 + 8758391 = 8758420
59 + 8758361 = 8758420
107 + 8758313 = 8758420
131 + 8758289 = 8758420
191 + 8758229 = 8758420
233 + 8758187 = 8758420
263 + 8758157 = 8758420
317 + 8758103 = 8758420

Showing the first eight; more decompositions exist.
