Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61398, here are decompositions:

17 + 61381 = 61398
19 + 61379 = 61398
41 + 61357 = 61398
59 + 61339 = 61398
67 + 61331 = 61398
101 + 61297 = 61398
107 + 61291 = 61398
137 + 61261 = 61398

Showing the first eight; more decompositions exist.
