Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40268, here are decompositions:
- 31 + 40237 = 40268
- 37 + 40231 = 40268
- 79 + 40189 = 40268
- 139 + 40129 = 40268
- 157 + 40111 = 40268
- 181 + 40087 = 40268
- 229 + 40039 = 40268
- 331 + 39937 = 40268
Showing the first eight; more decompositions exist.
