Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61222, here are decompositions:
- 11 + 61211 = 61222
- 53 + 61169 = 61222
- 71 + 61151 = 61222
- 101 + 61121 = 61222
- 131 + 61091 = 61222
- 179 + 61043 = 61222
- 191 + 61031 = 61222
- 269 + 60953 = 61222
Showing the first eight; more decompositions exist.
