Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68242, here are decompositions:

3 + 68239 = 68242
23 + 68219 = 68242
29 + 68213 = 68242
71 + 68171 = 68242
101 + 68141 = 68242
131 + 68111 = 68242
263 + 67979 = 68242
281 + 67961 = 68242

Showing the first eight; more decompositions exist.
