Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012478, here are decompositions:

31 + 1012447 = 1012478
67 + 1012411 = 1012478
79 + 1012399 = 1012478
109 + 1012369 = 1012478
157 + 1012321 = 1012478
199 + 1012279 = 1012478
211 + 1012267 = 1012478
277 + 1012201 = 1012478

Showing the first eight; more decompositions exist.
