Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739478, here are decompositions:

47 + 8739431 = 8739478
89 + 8739389 = 8739478
179 + 8739299 = 8739478
197 + 8739281 = 8739478
269 + 8739209 = 8739478
281 + 8739197 = 8739478
311 + 8739167 = 8739478
359 + 8739119 = 8739478

Showing the first eight; more decompositions exist.
