Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61408, here are decompositions:

5 + 61403 = 61408
29 + 61379 = 61408
197 + 61211 = 61408
239 + 61169 = 61408
257 + 61151 = 61408
317 + 61091 = 61408
401 + 61007 = 61408
491 + 60917 = 61408

Showing the first eight; more decompositions exist.
