Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739430, here are decompositions:

41 + 8739389 = 8739430
71 + 8739359 = 8739430
131 + 8739299 = 8739430
149 + 8739281 = 8739430
233 + 8739197 = 8739430
263 + 8739167 = 8739430
311 + 8739119 = 8739430
317 + 8739113 = 8739430

Showing the first eight; more decompositions exist.
