Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498870, here are decompositions:
- 3 + 31498867 = 31498870
- 17 + 31498853 = 31498870
- 23 + 31498847 = 31498870
- 41 + 31498829 = 31498870
- 59 + 31498811 = 31498870
- 107 + 31498763 = 31498870
- 167 + 31498703 = 31498870
- 311 + 31498559 = 31498870
Showing the first eight; more decompositions exist.
