Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143754, here are decompositions:

11 + 143743 = 143754
43 + 143711 = 143754
67 + 143687 = 143754
101 + 143653 = 143754
103 + 143651 = 143754
137 + 143617 = 143754
181 + 143573 = 143754
227 + 143527 = 143754

Showing the first eight; more decompositions exist.
