Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498108, here are decompositions:
- 101 + 31498007 = 31498108
- 167 + 31497941 = 31498108
- 179 + 31497929 = 31498108
- 281 + 31497827 = 31498108
- 311 + 31497797 = 31498108
- 401 + 31497707 = 31498108
- 557 + 31497551 = 31498108
- 617 + 31497491 = 31498108
Showing the first eight; more decompositions exist.
