Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534392, here are decompositions:
- 23 + 31534369 = 31534392
- 59 + 31534333 = 31534392
- 151 + 31534241 = 31534392
- 193 + 31534199 = 31534392
- 223 + 31534169 = 31534392
- 251 + 31534141 = 31534392
- 271 + 31534121 = 31534392
- 313 + 31534079 = 31534392
Showing the first eight; more decompositions exist.
