Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130838, here are decompositions:

31 + 130807 = 130838
109 + 130729 = 130838
139 + 130699 = 130838
151 + 130687 = 130838
157 + 130681 = 130838
181 + 130657 = 130838
199 + 130639 = 130838
307 + 130531 = 130838

Showing the first eight; more decompositions exist.
