Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739492, here are decompositions:

11 + 8739481 = 8739492
29 + 8739463 = 8739492
59 + 8739433 = 8739492
61 + 8739431 = 8739492
101 + 8739391 = 8739492
103 + 8739389 = 8739492
193 + 8739299 = 8739492
211 + 8739281 = 8739492

Showing the first eight; more decompositions exist.
