Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536040, here are decompositions:
- 23 + 31536017 = 31536040
- 59 + 31535981 = 31536040
- 101 + 31535939 = 31536040
- 131 + 31535909 = 31536040
- 293 + 31535747 = 31536040
- 359 + 31535681 = 31536040
- 383 + 31535657 = 31536040
- 401 + 31535639 = 31536040
Showing the first eight; more decompositions exist.
