Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529476, here are decompositions:
- 5 + 31529471 = 31529476
- 29 + 31529447 = 31529476
- 197 + 31529279 = 31529476
- 227 + 31529249 = 31529476
- 233 + 31529243 = 31529476
- 257 + 31529219 = 31529476
- 263 + 31529213 = 31529476
- 389 + 31529087 = 31529476
Showing the first eight; more decompositions exist.
