Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72356, here are decompositions:
- 3 + 72353 = 72356
- 19 + 72337 = 72356
- 43 + 72313 = 72356
- 79 + 72277 = 72356
- 103 + 72253 = 72356
- 127 + 72229 = 72356
- 283 + 72073 = 72356
- 313 + 72043 = 72356
Showing the first eight; more decompositions exist.
