Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023478, here are decompositions:

11 + 1023467 = 1023478
17 + 1023461 = 1023478
59 + 1023419 = 1023478
89 + 1023389 = 1023478
149 + 1023329 = 1023478
167 + 1023311 = 1023478
179 + 1023299 = 1023478
251 + 1023227 = 1023478

Showing the first eight; more decompositions exist.
