Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131754, here are decompositions:

5 + 131749 = 131754
11 + 131743 = 131754
23 + 131731 = 131754
41 + 131713 = 131754
43 + 131711 = 131754
47 + 131707 = 131754
53 + 131701 = 131754
67 + 131687 = 131754

Showing the first eight; more decompositions exist.
