Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540476, here are decompositions:
- 5 + 31540471 = 31540476
- 59 + 31540417 = 31540476
- 113 + 31540363 = 31540476
- 137 + 31540339 = 31540476
- 167 + 31540309 = 31540476
- 179 + 31540297 = 31540476
- 263 + 31540213 = 31540476
- 269 + 31540207 = 31540476
Showing the first eight; more decompositions exist.
