Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87746, here are decompositions:

3 + 87743 = 87746
7 + 87739 = 87746
67 + 87679 = 87746
97 + 87649 = 87746
103 + 87643 = 87746
157 + 87589 = 87746
163 + 87583 = 87746
193 + 87553 = 87746

Showing the first eight; more decompositions exist.
