Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 946640, here are decompositions:

61 + 946579 = 946640
67 + 946573 = 946640
127 + 946513 = 946640
151 + 946489 = 946640
181 + 946459 = 946640
223 + 946417 = 946640
229 + 946411 = 946640
271 + 946369 = 946640

Showing the first eight; more decompositions exist.
