Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525872, here are decompositions:
- 23 + 31525849 = 31525872
- 31 + 31525841 = 31525872
- 61 + 31525811 = 31525872
- 73 + 31525799 = 31525872
- 89 + 31525783 = 31525872
- 101 + 31525771 = 31525872
- 109 + 31525763 = 31525872
- 149 + 31525723 = 31525872
Showing the first eight; more decompositions exist.
