Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532722, here are decompositions:
- 29 + 31532693 = 31532722
- 83 + 31532639 = 31532722
- 149 + 31532573 = 31532722
- 233 + 31532489 = 31532722
- 293 + 31532429 = 31532722
- 383 + 31532339 = 31532722
- 443 + 31532279 = 31532722
- 461 + 31532261 = 31532722
Showing the first eight; more decompositions exist.
