Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61658, here are decompositions:

7 + 61651 = 61658
31 + 61627 = 61658
97 + 61561 = 61658
139 + 61519 = 61658
151 + 61507 = 61658
241 + 61417 = 61658
277 + 61381 = 61658
367 + 61291 = 61658

Showing the first eight; more decompositions exist.
