Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61228, here are decompositions:

5 + 61223 = 61228
17 + 61211 = 61228
59 + 61169 = 61228
107 + 61121 = 61228
137 + 61091 = 61228
197 + 61031 = 61228
227 + 61001 = 61228
311 + 60917 = 61228

Showing the first eight; more decompositions exist.
