Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988684, here are decompositions:

3 + 988681 = 988684
23 + 988661 = 988684
41 + 988643 = 988684
101 + 988583 = 988684
107 + 988577 = 988684
113 + 988571 = 988684
173 + 988511 = 988684
317 + 988367 = 988684

Showing the first eight; more decompositions exist.
