Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534356, here are decompositions:
- 13 + 31534343 = 31534356
- 23 + 31534333 = 31534356
- 59 + 31534297 = 31534356
- 109 + 31534247 = 31534356
- 157 + 31534199 = 31534356
- 173 + 31534183 = 31534356
- 239 + 31534117 = 31534356
- 277 + 31534079 = 31534356
Showing the first eight; more decompositions exist.
