Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87626, here are decompositions:

3 + 87623 = 87626
13 + 87613 = 87626
37 + 87589 = 87626
43 + 87583 = 87626
67 + 87559 = 87626
73 + 87553 = 87626
79 + 87547 = 87626
103 + 87523 = 87626

Showing the first eight; more decompositions exist.
