Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30626, here are decompositions:
- 67 + 30559 = 30626
- 73 + 30553 = 30626
- 97 + 30529 = 30626
- 109 + 30517 = 30626
- 157 + 30469 = 30626
- 199 + 30427 = 30626
- 223 + 30403 = 30626
- 307 + 30319 = 30626
Showing the first eight; more decompositions exist.
