Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70722, here are decompositions:
- 5 + 70717 = 70722
- 13 + 70709 = 70722
- 59 + 70663 = 70722
- 83 + 70639 = 70722
- 101 + 70621 = 70722
- 103 + 70619 = 70722
- 139 + 70583 = 70722
- 149 + 70573 = 70722
Showing the first eight; more decompositions exist.
