Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133580, here are decompositions:

37 + 133543 = 133580
61 + 133519 = 133580
163 + 133417 = 133580
193 + 133387 = 133580
229 + 133351 = 133580
277 + 133303 = 133580
367 + 133213 = 133580
379 + 133201 = 133580

Showing the first eight; more decompositions exist.
