Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51636, here are decompositions:
- 5 + 51631 = 51636
- 23 + 51613 = 51636
- 29 + 51607 = 51636
- 37 + 51599 = 51636
- 43 + 51593 = 51636
- 59 + 51577 = 51636
- 73 + 51563 = 51636
- 97 + 51539 = 51636
Showing the first eight; more decompositions exist.
