Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535500, here are decompositions:
- 71 + 31535429 = 31535500
- 83 + 31535417 = 31535500
- 89 + 31535411 = 31535500
- 173 + 31535327 = 31535500
- 179 + 31535321 = 31535500
- 281 + 31535219 = 31535500
- 317 + 31535183 = 31535500
- 419 + 31535081 = 31535500
Showing the first eight; more decompositions exist.
