Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130906, here are decompositions:

47 + 130859 = 130906
89 + 130817 = 130906
137 + 130769 = 130906
257 + 130649 = 130906
263 + 130643 = 130906
317 + 130589 = 130906
353 + 130553 = 130906
359 + 130547 = 130906

Showing the first eight; more decompositions exist.
