Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013686, here are decompositions:

5 + 1013681 = 1013686
59 + 1013627 = 1013686
83 + 1013603 = 1013686
257 + 1013429 = 1013686
419 + 1013267 = 1013686
449 + 1013237 = 1013686
677 + 1013009 = 1013686
683 + 1013003 = 1013686

Showing the first eight; more decompositions exist.
