Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739538, here are decompositions:

47 + 8739491 = 8739538
107 + 8739431 = 8739538
149 + 8739389 = 8739538
179 + 8739359 = 8739538
239 + 8739299 = 8739538
257 + 8739281 = 8739538
419 + 8739119 = 8739538
701 + 8738837 = 8739538

Showing the first eight; more decompositions exist.
