Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51620, here are decompositions:
- 7 + 51613 = 51620
- 13 + 51607 = 51620
- 43 + 51577 = 51620
- 103 + 51517 = 51620
- 109 + 51511 = 51620
- 139 + 51481 = 51620
- 181 + 51439 = 51620
- 193 + 51427 = 51620
Showing the first eight; more decompositions exist.
