Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533276, here are decompositions:
- 7 + 31533269 = 31533276
- 17 + 31533259 = 31533276
- 67 + 31533209 = 31533276
- 109 + 31533167 = 31533276
- 127 + 31533149 = 31533276
- 149 + 31533127 = 31533276
- 157 + 31533119 = 31533276
- 179 + 31533097 = 31533276
Showing the first eight; more decompositions exist.
