Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739394, here are decompositions:

3 + 8739391 = 8739394
5 + 8739389 = 8739394
113 + 8739281 = 8739394
197 + 8739197 = 8739394
227 + 8739167 = 8739394
281 + 8739113 = 8739394
431 + 8738963 = 8739394
557 + 8738837 = 8739394

Showing the first eight; more decompositions exist.
