Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130168, here are decompositions:

41 + 130127 = 130168
47 + 130121 = 130168
89 + 130079 = 130168
197 + 129971 = 130168
251 + 129917 = 130168
281 + 129887 = 130168
419 + 129749 = 130168
431 + 129737 = 130168

Showing the first eight; more decompositions exist.
