Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30542, here are decompositions:
- 3 + 30539 = 30542
- 13 + 30529 = 30542
- 73 + 30469 = 30542
- 139 + 30403 = 30542
- 151 + 30391 = 30542
- 223 + 30319 = 30542
- 229 + 30313 = 30542
- 271 + 30271 = 30542
Showing the first eight; more decompositions exist.
