Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535350, here are decompositions:
- 23 + 31535327 = 31535350
- 29 + 31535321 = 31535350
- 131 + 31535219 = 31535350
- 137 + 31535213 = 31535350
- 167 + 31535183 = 31535350
- 179 + 31535171 = 31535350
- 227 + 31535123 = 31535350
- 269 + 31535081 = 31535350
Showing the first eight; more decompositions exist.
