Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51396, here are decompositions:
- 13 + 51383 = 51396
- 47 + 51349 = 51396
- 53 + 51343 = 51396
- 67 + 51329 = 51396
- 89 + 51307 = 51396
- 109 + 51287 = 51396
- 113 + 51283 = 51396
- 139 + 51257 = 51396
Showing the first eight; more decompositions exist.
