Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543204, here are decompositions:
- 23 + 31543181 = 31543204
- 41 + 31543163 = 31543204
- 71 + 31543133 = 31543204
- 101 + 31543103 = 31543204
- 137 + 31543067 = 31543204
- 233 + 31542971 = 31543204
- 263 + 31542941 = 31543204
- 293 + 31542911 = 31543204
Showing the first eight; more decompositions exist.
