Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72226, here are decompositions:
- 3 + 72223 = 72226
- 5 + 72221 = 72226
- 53 + 72173 = 72226
- 59 + 72167 = 72226
- 137 + 72089 = 72226
- 149 + 72077 = 72226
- 173 + 72053 = 72226
- 179 + 72047 = 72226
Showing the first eight; more decompositions exist.
