Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61224, here are decompositions:
- 13 + 61211 = 61224
- 71 + 61153 = 61224
- 73 + 61151 = 61224
- 83 + 61141 = 61224
- 103 + 61121 = 61224
- 167 + 61057 = 61224
- 173 + 61051 = 61224
- 181 + 61043 = 61224
Showing the first eight; more decompositions exist.
