Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61388, here are decompositions:

7 + 61381 = 61388
31 + 61357 = 61388
97 + 61291 = 61388
127 + 61261 = 61388
157 + 61231 = 61388
331 + 61057 = 61388
337 + 61051 = 61388
487 + 60901 = 61388

Showing the first eight; more decompositions exist.
