Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739472, here are decompositions:

41 + 8739431 = 8739472
83 + 8739389 = 8739472
113 + 8739359 = 8739472
173 + 8739299 = 8739472
191 + 8739281 = 8739472
263 + 8739209 = 8739472
353 + 8739119 = 8739472
359 + 8739113 = 8739472

Showing the first eight; more decompositions exist.
