Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30722, here are decompositions:
- 19 + 30703 = 30722
- 61 + 30661 = 30722
- 73 + 30649 = 30722
- 79 + 30643 = 30722
- 163 + 30559 = 30722
- 193 + 30529 = 30722
- 229 + 30493 = 30722
- 331 + 30391 = 30722
Showing the first eight; more decompositions exist.
