Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72254, here are decompositions:
- 3 + 72251 = 72254
- 31 + 72223 = 72254
- 43 + 72211 = 72254
- 151 + 72103 = 72254
- 163 + 72091 = 72254
- 181 + 72073 = 72254
- 211 + 72043 = 72254
- 223 + 72031 = 72254
Showing the first eight; more decompositions exist.
