Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130850, here are decompositions:

7 + 130843 = 130850
43 + 130807 = 130850
67 + 130783 = 130850
151 + 130699 = 130850
157 + 130693 = 130850
163 + 130687 = 130850
193 + 130657 = 130850
199 + 130651 = 130850

Showing the first eight; more decompositions exist.
