Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988586, here are decompositions:

3 + 988583 = 988586
7 + 988579 = 988586
37 + 988549 = 988586
97 + 988489 = 988586
103 + 988483 = 988586
127 + 988459 = 988586
229 + 988357 = 988586
307 + 988279 = 988586

Showing the first eight; more decompositions exist.
