Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61538, here are decompositions:

19 + 61519 = 61538
31 + 61507 = 61538
67 + 61471 = 61538
97 + 61441 = 61538
157 + 61381 = 61538
181 + 61357 = 61538
199 + 61339 = 61538
241 + 61297 = 61538

Showing the first eight; more decompositions exist.
