Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031978, here are decompositions:

67 + 1031911 = 1031978
109 + 1031869 = 1031978
271 + 1031707 = 1031978
349 + 1031629 = 1031978
457 + 1031521 = 1031978
499 + 1031479 = 1031978
547 + 1031431 = 1031978
631 + 1031347 = 1031978

Showing the first eight; more decompositions exist.
