Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35640, here are decompositions:
- 23 + 35617 = 35640
- 37 + 35603 = 35640
- 43 + 35597 = 35640
- 47 + 35593 = 35640
- 67 + 35573 = 35640
- 71 + 35569 = 35640
- 97 + 35543 = 35640
- 103 + 35537 = 35640
Showing the first eight; more decompositions exist.
