Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61242, here are decompositions:

11 + 61231 = 61242
19 + 61223 = 61242
31 + 61211 = 61242
73 + 61169 = 61242
89 + 61153 = 61242
101 + 61141 = 61242
113 + 61129 = 61242
151 + 61091 = 61242

Showing the first eight; more decompositions exist.
