Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157710, here are decompositions:

31 + 157679 = 157710
41 + 157669 = 157710
43 + 157667 = 157710
61 + 157649 = 157710
71 + 157639 = 157710
73 + 157637 = 157710
83 + 157627 = 157710
131 + 157579 = 157710

Showing the first eight; more decompositions exist.
