Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045894, here are decompositions:

53 + 1045841 = 1045894
131 + 1045763 = 1045894
167 + 1045727 = 1045894
251 + 1045643 = 1045894
347 + 1045547 = 1045894
401 + 1045493 = 1045894
467 + 1045427 = 1045894
503 + 1045391 = 1045894

Showing the first eight; more decompositions exist.
