Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498106, here are decompositions:
- 19 + 31498087 = 31498106
- 37 + 31498069 = 31498106
- 67 + 31498039 = 31498106
- 97 + 31498009 = 31498106
- 103 + 31498003 = 31498106
- 109 + 31497997 = 31498106
- 127 + 31497979 = 31498106
- 223 + 31497883 = 31498106
Showing the first eight; more decompositions exist.
