Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157746, here are decompositions:

7 + 157739 = 157746
13 + 157733 = 157746
67 + 157679 = 157746
79 + 157667 = 157746
97 + 157649 = 157746
107 + 157639 = 157746
109 + 157637 = 157746
167 + 157579 = 157746

Showing the first eight; more decompositions exist.
