Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130446, here are decompositions:

7 + 130439 = 130446
23 + 130423 = 130446
37 + 130409 = 130446
47 + 130399 = 130446
67 + 130379 = 130446
79 + 130367 = 130446
83 + 130363 = 130446
97 + 130349 = 130446

Showing the first eight; more decompositions exist.
