Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51556, here are decompositions:
- 5 + 51551 = 51556
- 17 + 51539 = 51556
- 53 + 51503 = 51556
- 83 + 51473 = 51556
- 107 + 51449 = 51556
- 137 + 51419 = 51556
- 149 + 51407 = 51556
- 173 + 51383 = 51556
Showing the first eight; more decompositions exist.
