Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534236, here are decompositions:
- 5 + 31534231 = 31534236
- 37 + 31534199 = 31534236
- 53 + 31534183 = 31534236
- 67 + 31534169 = 31534236
- 157 + 31534079 = 31534236
- 163 + 31534073 = 31534236
- 179 + 31534057 = 31534236
- 257 + 31533979 = 31534236
Showing the first eight; more decompositions exist.
