Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023778, here are decompositions:

47 + 1023731 = 1023778
59 + 1023719 = 1023778
227 + 1023551 = 1023778
257 + 1023521 = 1023778
311 + 1023467 = 1023778
317 + 1023461 = 1023778
359 + 1023419 = 1023778
389 + 1023389 = 1023778

Showing the first eight; more decompositions exist.
