Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489084, here are decompositions:
- 5 + 31489079 = 31489084
- 41 + 31489043 = 31489084
- 47 + 31489037 = 31489084
- 113 + 31488971 = 31489084
- 167 + 31488917 = 31489084
- 173 + 31488911 = 31489084
- 257 + 31488827 = 31489084
- 317 + 31488767 = 31489084
Showing the first eight; more decompositions exist.
