Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758428, here are decompositions:

37 + 8758391 = 8758428
67 + 8758361 = 8758428
89 + 8758339 = 8758428
101 + 8758327 = 8758428
139 + 8758289 = 8758428
149 + 8758279 = 8758428
199 + 8758229 = 8758428
227 + 8758201 = 8758428

Showing the first eight; more decompositions exist.
