Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61688, here are decompositions:

7 + 61681 = 61688
31 + 61657 = 61688
37 + 61651 = 61688
61 + 61627 = 61688
79 + 61609 = 61688
127 + 61561 = 61688
181 + 61507 = 61688
271 + 61417 = 61688

Showing the first eight; more decompositions exist.
