Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30572, here are decompositions:
- 13 + 30559 = 30572
- 19 + 30553 = 30572
- 43 + 30529 = 30572
- 79 + 30493 = 30572
- 103 + 30469 = 30572
- 181 + 30391 = 30572
- 313 + 30259 = 30572
- 331 + 30241 = 30572
Showing the first eight; more decompositions exist.
