Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131814, here are decompositions:

17 + 131797 = 131814
31 + 131783 = 131814
37 + 131777 = 131814
43 + 131771 = 131814
71 + 131743 = 131814
83 + 131731 = 131814
101 + 131713 = 131814
103 + 131711 = 131814

Showing the first eight; more decompositions exist.
