Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61212, here are decompositions:

43 + 61169 = 61212
59 + 61153 = 61212
61 + 61151 = 61212
71 + 61141 = 61212
83 + 61129 = 61212
113 + 61099 = 61212
181 + 61031 = 61212
211 + 61001 = 61212

Showing the first eight; more decompositions exist.
