Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72416, here are decompositions:
- 37 + 72379 = 72416
- 79 + 72337 = 72416
- 103 + 72313 = 72416
- 109 + 72307 = 72416
- 139 + 72277 = 72416
- 163 + 72253 = 72416
- 193 + 72223 = 72416
- 277 + 72139 = 72416
Showing the first eight; more decompositions exist.
