Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045722, here are decompositions:

31 + 1045691 = 1045722
43 + 1045679 = 1045722
59 + 1045663 = 1045722
71 + 1045651 = 1045722
79 + 1045643 = 1045722
89 + 1045633 = 1045722
101 + 1045621 = 1045722
149 + 1045573 = 1045722

Showing the first eight; more decompositions exist.
