Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497850, here are decompositions:
- 23 + 31497827 = 31497850
- 47 + 31497803 = 31497850
- 53 + 31497797 = 31497850
- 113 + 31497737 = 31497850
- 149 + 31497701 = 31497850
- 179 + 31497671 = 31497850
- 281 + 31497569 = 31497850
- 359 + 31497491 = 31497850
Showing the first eight; more decompositions exist.
