Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10838, here are decompositions:
- 7 + 10831 = 10838
- 67 + 10771 = 10838
- 109 + 10729 = 10838
- 127 + 10711 = 10838
- 151 + 10687 = 10838
- 181 + 10657 = 10838
- 199 + 10639 = 10838
- 211 + 10627 = 10838
Showing the first eight; more decompositions exist.
