Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531084, here are decompositions:
- 5 + 31531079 = 31531084
- 83 + 31531001 = 31531084
- 107 + 31530977 = 31531084
- 191 + 31530893 = 31531084
- 251 + 31530833 = 31531084
- 257 + 31530827 = 31531084
- 311 + 31530773 = 31531084
- 383 + 31530701 = 31531084
Showing the first eight; more decompositions exist.
