Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961580, here are decompositions:

13 + 961567 = 961580
31 + 961549 = 961580
73 + 961507 = 961580
127 + 961453 = 961580
181 + 961399 = 961580
241 + 961339 = 961580
307 + 961273 = 961580
337 + 961243 = 961580

Showing the first eight; more decompositions exist.
