Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535496, here are decompositions:
- 29 + 31535467 = 31535496
- 67 + 31535429 = 31535496
- 73 + 31535423 = 31535496
- 79 + 31535417 = 31535496
- 233 + 31535263 = 31535496
- 263 + 31535233 = 31535496
- 269 + 31535227 = 31535496
- 277 + 31535219 = 31535496
Showing the first eight; more decompositions exist.
