Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498850, here are decompositions:
- 3 + 31498847 = 31498850
- 13 + 31498837 = 31498850
- 37 + 31498813 = 31498850
- 109 + 31498741 = 31498850
- 193 + 31498657 = 31498850
- 211 + 31498639 = 31498850
- 337 + 31498513 = 31498850
- 379 + 31498471 = 31498850
Showing the first eight; more decompositions exist.
