Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612628, here are decompositions:

47 + 8612581 = 8612628
97 + 8612531 = 8612628
131 + 8612497 = 8612628
149 + 8612479 = 8612628
191 + 8612437 = 8612628
229 + 8612399 = 8612628
281 + 8612347 = 8612628
317 + 8612311 = 8612628

Showing the first eight; more decompositions exist.
