Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130918, here are decompositions:

59 + 130859 = 130918
89 + 130829 = 130918
101 + 130817 = 130918
107 + 130811 = 130918
131 + 130787 = 130918
149 + 130769 = 130918
269 + 130649 = 130918
401 + 130517 = 130918

Showing the first eight; more decompositions exist.
