Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738586, here are decompositions:

5 + 8738581 = 8738586
7 + 8738579 = 8738586
19 + 8738567 = 8738586
47 + 8738539 = 8738586
53 + 8738533 = 8738586
79 + 8738507 = 8738586
113 + 8738473 = 8738586
137 + 8738449 = 8738586

Showing the first eight; more decompositions exist.
