Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498196, here are decompositions:
- 3 + 31498193 = 31498196
- 7 + 31498189 = 31498196
- 73 + 31498123 = 31498196
- 109 + 31498087 = 31498196
- 127 + 31498069 = 31498196
- 157 + 31498039 = 31498196
- 193 + 31498003 = 31498196
- 199 + 31497997 = 31498196
Showing the first eight; more decompositions exist.
