Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143778, here are decompositions:

59 + 143719 = 143778
67 + 143711 = 143778
79 + 143699 = 143778
101 + 143677 = 143778
109 + 143669 = 143778
127 + 143651 = 143778
149 + 143629 = 143778
211 + 143567 = 143778

Showing the first eight; more decompositions exist.
