Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85818, here are decompositions:
- 37 + 85781 = 85818
- 67 + 85751 = 85818
- 101 + 85717 = 85818
- 107 + 85711 = 85818
- 127 + 85691 = 85818
- 149 + 85669 = 85818
- 151 + 85667 = 85818
- 157 + 85661 = 85818
Showing the first eight; more decompositions exist.
