Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130450, here are decompositions:

3 + 130447 = 130450
11 + 130439 = 130450
41 + 130409 = 130450
71 + 130379 = 130450
83 + 130367 = 130450
101 + 130349 = 130450
107 + 130343 = 130450
113 + 130337 = 130450

Showing the first eight; more decompositions exist.
