Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540332, here are decompositions:
- 23 + 31540309 = 31540332
- 71 + 31540261 = 31540332
- 151 + 31540181 = 31540332
- 223 + 31540109 = 31540332
- 233 + 31540099 = 31540332
- 269 + 31540063 = 31540332
- 401 + 31539931 = 31540332
- 431 + 31539901 = 31540332
Showing the first eight; more decompositions exist.
