Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740492, here are decompositions:

191 + 8740301 = 8740492
353 + 8740139 = 8740492
641 + 8739851 = 8740492
743 + 8739749 = 8740492
821 + 8739671 = 8740492
1061 + 8739431 = 8740492
1103 + 8739389 = 8740492
1193 + 8739299 = 8740492

Showing the first eight; more decompositions exist.
