Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547904, here are decompositions:
- 43 + 31547861 = 31547904
- 53 + 31547851 = 31547904
- 67 + 31547837 = 31547904
- 71 + 31547833 = 31547904
- 173 + 31547731 = 31547904
- 197 + 31547707 = 31547904
- 211 + 31547693 = 31547904
- 233 + 31547671 = 31547904
Showing the first eight; more decompositions exist.
