Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627476, here are decompositions:
- 103 + 31627373 = 31627476
- 157 + 31627319 = 31627476
- 173 + 31627303 = 31627476
- 227 + 31627249 = 31627476
- 229 + 31627247 = 31627476
- 233 + 31627243 = 31627476
- 239 + 31627237 = 31627476
- 443 + 31627033 = 31627476
Showing the first eight; more decompositions exist.
