Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045242, here are decompositions:

5 + 1045237 = 1045242
13 + 1045229 = 1045242
19 + 1045223 = 1045242
43 + 1045199 = 1045242
59 + 1045183 = 1045242
89 + 1045153 = 1045242
113 + 1045129 = 1045242
131 + 1045111 = 1045242

Showing the first eight; more decompositions exist.
