Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739486, here are decompositions:

5 + 8739481 = 8739486
23 + 8739463 = 8739486
53 + 8739433 = 8739486
89 + 8739397 = 8739486
97 + 8739389 = 8739486
127 + 8739359 = 8739486
137 + 8739349 = 8739486
149 + 8739337 = 8739486

Showing the first eight; more decompositions exist.
