Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 968138, here are decompositions:

37 + 968101 = 968138
97 + 968041 = 968138
139 + 967999 = 968138
307 + 967831 = 968138
439 + 967699 = 968138
571 + 967567 = 968138
631 + 967507 = 968138
709 + 967429 = 968138

Showing the first eight; more decompositions exist.
