Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739420, here are decompositions:

23 + 8739397 = 8739420
29 + 8739391 = 8739420
31 + 8739389 = 8739420
61 + 8739359 = 8739420
71 + 8739349 = 8739420
83 + 8739337 = 8739420
89 + 8739331 = 8739420
139 + 8739281 = 8739420

Showing the first eight; more decompositions exist.
