Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525830, here are decompositions:
- 13 + 31525817 = 31525830
- 19 + 31525811 = 31525830
- 31 + 31525799 = 31525830
- 43 + 31525787 = 31525830
- 47 + 31525783 = 31525830
- 53 + 31525777 = 31525830
- 59 + 31525771 = 31525830
- 67 + 31525763 = 31525830
Showing the first eight; more decompositions exist.
