Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72266, here are decompositions:
- 13 + 72253 = 72266
- 37 + 72229 = 72266
- 43 + 72223 = 72266
- 97 + 72169 = 72266
- 127 + 72139 = 72266
- 157 + 72109 = 72266
- 163 + 72103 = 72266
- 193 + 72073 = 72266
Showing the first eight; more decompositions exist.
