Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41640, here are decompositions:
- 13 + 41627 = 41640
- 19 + 41621 = 41640
- 23 + 41617 = 41640
- 29 + 41611 = 41640
- 31 + 41609 = 41640
- 37 + 41603 = 41640
- 43 + 41597 = 41640
- 47 + 41593 = 41640
Showing the first eight; more decompositions exist.
