Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131012, here are decompositions:

3 + 131009 = 131012
31 + 130981 = 131012
43 + 130969 = 131012
139 + 130873 = 131012
229 + 130783 = 131012
283 + 130729 = 131012
313 + 130699 = 131012
331 + 130681 = 131012

Showing the first eight; more decompositions exist.
