Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526872, here are decompositions:
- 53 + 31526819 = 31526872
- 101 + 31526771 = 31526872
- 149 + 31526723 = 31526872
- 239 + 31526633 = 31526872
- 269 + 31526603 = 31526872
- 383 + 31526489 = 31526872
- 449 + 31526423 = 31526872
- 521 + 31526351 = 31526872
Showing the first eight; more decompositions exist.
