Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747430, here are decompositions:

7 + 8747423 = 8747430
11 + 8747419 = 8747430
23 + 8747407 = 8747430
101 + 8747329 = 8747430
103 + 8747327 = 8747430
157 + 8747273 = 8747430
173 + 8747257 = 8747430
179 + 8747251 = 8747430

Showing the first eight; more decompositions exist.
