Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712430, here are decompositions:

59 + 8712371 = 8712430
107 + 8712323 = 8712430
137 + 8712293 = 8712430
149 + 8712281 = 8712430
173 + 8712257 = 8712430
197 + 8712233 = 8712430
257 + 8712173 = 8712430
263 + 8712167 = 8712430

Showing the first eight; more decompositions exist.
