Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045230, here are decompositions:

7 + 1045223 = 1045230
31 + 1045199 = 1045230
37 + 1045193 = 1045230
47 + 1045183 = 1045230
73 + 1045157 = 1045230
79 + 1045151 = 1045230
101 + 1045129 = 1045230
107 + 1045123 = 1045230

Showing the first eight; more decompositions exist.
