Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143742, here are decompositions:

13 + 143729 = 143742
23 + 143719 = 143742
31 + 143711 = 143742
43 + 143699 = 143742
73 + 143669 = 143742
89 + 143653 = 143742
113 + 143629 = 143742
149 + 143593 = 143742

Showing the first eight; more decompositions exist.
