Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72236, here are decompositions:
- 7 + 72229 = 72236
- 13 + 72223 = 72236
- 67 + 72169 = 72236
- 97 + 72139 = 72236
- 127 + 72109 = 72236
- 163 + 72073 = 72236
- 193 + 72043 = 72236
- 337 + 71899 = 72236
Showing the first eight; more decompositions exist.
