Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739450, here are decompositions:

17 + 8739433 = 8739450
19 + 8739431 = 8739450
53 + 8739397 = 8739450
59 + 8739391 = 8739450
61 + 8739389 = 8739450
101 + 8739349 = 8739450
113 + 8739337 = 8739450
151 + 8739299 = 8739450

Showing the first eight; more decompositions exist.
