Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045788, here are decompositions:

59 + 1045729 = 1045788
61 + 1045727 = 1045788
97 + 1045691 = 1045788
109 + 1045679 = 1045788
137 + 1045651 = 1045788
167 + 1045621 = 1045788
181 + 1045607 = 1045788
229 + 1045559 = 1045788

Showing the first eight; more decompositions exist.
