Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72670, here are decompositions:
- 23 + 72647 = 72670
- 47 + 72623 = 72670
- 53 + 72617 = 72670
- 137 + 72533 = 72670
- 167 + 72503 = 72670
- 173 + 72497 = 72670
- 239 + 72431 = 72670
- 317 + 72353 = 72670
Showing the first eight; more decompositions exist.
