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.
