Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30618, here are decompositions:
- 41 + 30577 = 30618
- 59 + 30559 = 30618
- 61 + 30557 = 30618
- 79 + 30539 = 30618
- 89 + 30529 = 30618
- 101 + 30517 = 30618
- 109 + 30509 = 30618
- 127 + 30491 = 30618
Showing the first eight; more decompositions exist.
