Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606432, here are decompositions:
- 3 + 31606429 = 31606432
- 59 + 31606373 = 31606432
- 89 + 31606343 = 31606432
- 101 + 31606331 = 31606432
- 113 + 31606319 = 31606432
- 149 + 31606283 = 31606432
- 251 + 31606181 = 31606432
- 353 + 31606079 = 31606432
Showing the first eight; more decompositions exist.
