Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61966, here are decompositions:

5 + 61961 = 61966
17 + 61949 = 61966
263 + 61703 = 61966
293 + 61673 = 61966
353 + 61613 = 61966
383 + 61583 = 61966
419 + 61547 = 61966
479 + 61487 = 61966

Showing the first eight; more decompositions exist.
