Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61508, here are decompositions:

37 + 61471 = 61508
67 + 61441 = 61508
127 + 61381 = 61508
151 + 61357 = 61508
211 + 61297 = 61508
277 + 61231 = 61508
367 + 61141 = 61508
379 + 61129 = 61508

Showing the first eight; more decompositions exist.
