Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544870, here are decompositions:
- 13 + 31544857 = 31544870
- 43 + 31544827 = 31544870
- 151 + 31544719 = 31544870
- 157 + 31544713 = 31544870
- 283 + 31544587 = 31544870
- 337 + 31544533 = 31544870
- 499 + 31544371 = 31544870
- 523 + 31544347 = 31544870
Showing the first eight; more decompositions exist.
