Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740430, here are decompositions:

3 + 8740427 = 8740430
19 + 8740411 = 8740430
37 + 8740393 = 8740430
43 + 8740387 = 8740430
103 + 8740327 = 8740430
109 + 8740321 = 8740430
157 + 8740273 = 8740430
211 + 8740219 = 8740430

Showing the first eight; more decompositions exist.
