Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64880, here are decompositions:

3 + 64877 = 64880
31 + 64849 = 64880
97 + 64783 = 64880
163 + 64717 = 64880
271 + 64609 = 64880
313 + 64567 = 64880
367 + 64513 = 64880
397 + 64483 = 64880

Showing the first eight; more decompositions exist.
