Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124242, here are decompositions:

11 + 124231 = 124242
29 + 124213 = 124242
43 + 124199 = 124242
59 + 124183 = 124242
61 + 124181 = 124242
71 + 124171 = 124242
89 + 124153 = 124242
103 + 124139 = 124242

Showing the first eight; more decompositions exist.
