Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043242, here are decompositions:

29 + 1043213 = 1043242
41 + 1043201 = 1043242
59 + 1043183 = 1043242
131 + 1043111 = 1043242
281 + 1042961 = 1043242
293 + 1042949 = 1043242
311 + 1042931 = 1043242
443 + 1042799 = 1043242

Showing the first eight; more decompositions exist.
