Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130778, here are decompositions:

79 + 130699 = 130778
97 + 130681 = 130778
127 + 130651 = 130778
139 + 130639 = 130778
157 + 130621 = 130778
199 + 130579 = 130778
331 + 130447 = 130778
367 + 130411 = 130778

Showing the first eight; more decompositions exist.
