Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61240, here are decompositions:
- 17 + 61223 = 61240
- 29 + 61211 = 61240
- 71 + 61169 = 61240
- 89 + 61151 = 61240
- 149 + 61091 = 61240
- 197 + 61043 = 61240
- 233 + 61007 = 61240
- 239 + 61001 = 61240
Showing the first eight; more decompositions exist.
