Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42654, here are decompositions:
- 5 + 42649 = 42654
- 11 + 42643 = 42654
- 13 + 42641 = 42654
- 43 + 42611 = 42654
- 83 + 42571 = 42654
- 97 + 42557 = 42654
- 163 + 42491 = 42654
- 167 + 42487 = 42654
Showing the first eight; more decompositions exist.
