Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945522, here are decompositions:

41 + 945481 = 945522
43 + 945479 = 945522
59 + 945463 = 945522
113 + 945409 = 945522
131 + 945391 = 945522
163 + 945359 = 945522
173 + 945349 = 945522
181 + 945341 = 945522

Showing the first eight; more decompositions exist.
