Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532402, here are decompositions:
- 61 + 31532341 = 31532402
- 73 + 31532329 = 31532402
- 79 + 31532323 = 31532402
- 193 + 31532209 = 31532402
- 199 + 31532203 = 31532402
- 313 + 31532089 = 31532402
- 331 + 31532071 = 31532402
- 823 + 31531579 = 31532402
Showing the first eight; more decompositions exist.
