Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61228, here are decompositions:
- 5 + 61223 = 61228
- 17 + 61211 = 61228
- 59 + 61169 = 61228
- 107 + 61121 = 61228
- 137 + 61091 = 61228
- 197 + 61031 = 61228
- 227 + 61001 = 61228
- 311 + 60917 = 61228
Showing the first eight; more decompositions exist.
