Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013578, here are decompositions:

47 + 1013531 = 1013578
101 + 1013477 = 1013578
107 + 1013471 = 1013578
149 + 1013429 = 1013578
179 + 1013399 = 1013578
257 + 1013321 = 1013578
311 + 1013267 = 1013578
569 + 1013009 = 1013578

Showing the first eight; more decompositions exist.
