Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72296, here are decompositions:
- 19 + 72277 = 72296
- 43 + 72253 = 72296
- 67 + 72229 = 72296
- 73 + 72223 = 72296
- 127 + 72169 = 72296
- 157 + 72139 = 72296
- 193 + 72103 = 72296
- 223 + 72073 = 72296
Showing the first eight; more decompositions exist.
