Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143634, here are decompositions:

5 + 143629 = 143634
17 + 143617 = 143634
41 + 143593 = 143634
61 + 143573 = 143634
67 + 143567 = 143634
83 + 143551 = 143634
97 + 143537 = 143634
107 + 143527 = 143634

Showing the first eight; more decompositions exist.
