Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540406, here are decompositions:
- 43 + 31540363 = 31540406
- 67 + 31540339 = 31540406
- 97 + 31540309 = 31540406
- 109 + 31540297 = 31540406
- 193 + 31540213 = 31540406
- 199 + 31540207 = 31540406
- 283 + 31540123 = 31540406
- 307 + 31540099 = 31540406
Showing the first eight; more decompositions exist.
