Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40242, here are decompositions:

5 + 40237 = 40242
11 + 40231 = 40242
29 + 40213 = 40242
53 + 40189 = 40242
73 + 40169 = 40242
79 + 40163 = 40242
89 + 40153 = 40242
113 + 40129 = 40242

Showing the first eight; more decompositions exist.
