Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42690, here are decompositions:
- 7 + 42683 = 42690
- 13 + 42677 = 42690
- 23 + 42667 = 42690
- 41 + 42649 = 42690
- 47 + 42643 = 42690
- 79 + 42611 = 42690
- 101 + 42589 = 42690
- 113 + 42577 = 42690
Showing the first eight; more decompositions exist.
