Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526590, here are decompositions:
- 101 + 31526489 = 31526590
- 113 + 31526477 = 31526590
- 167 + 31526423 = 31526590
- 239 + 31526351 = 31526590
- 317 + 31526273 = 31526590
- 383 + 31526207 = 31526590
- 401 + 31526189 = 31526590
- 449 + 31526141 = 31526590
Showing the first eight; more decompositions exist.
