Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42648, here are decompositions:
- 5 + 42643 = 42648
- 7 + 42641 = 42648
- 37 + 42611 = 42648
- 59 + 42589 = 42648
- 71 + 42577 = 42648
- 79 + 42569 = 42648
- 139 + 42509 = 42648
- 149 + 42499 = 42648
Showing the first eight; more decompositions exist.
