Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42672, here are decompositions:
- 5 + 42667 = 42672
- 23 + 42649 = 42672
- 29 + 42643 = 42672
- 31 + 42641 = 42672
- 61 + 42611 = 42672
- 83 + 42589 = 42672
- 101 + 42571 = 42672
- 103 + 42569 = 42672
Showing the first eight; more decompositions exist.
