Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542652, here are decompositions:
- 173 + 31542479 = 31542652
- 233 + 31542419 = 31542652
- 293 + 31542359 = 31542652
- 311 + 31542341 = 31542652
- 419 + 31542233 = 31542652
- 503 + 31542149 = 31542652
- 569 + 31542083 = 31542652
- 641 + 31542011 = 31542652
Showing the first eight; more decompositions exist.
