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.
