Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130742, here are decompositions:

13 + 130729 = 130742
43 + 130699 = 130742
61 + 130681 = 130742
103 + 130639 = 130742
109 + 130633 = 130742
163 + 130579 = 130742
211 + 130531 = 130742
229 + 130513 = 130742

Showing the first eight; more decompositions exist.
