Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496166, here are decompositions:
- 5 + 31496161 = 31496166
- 43 + 31496123 = 31496166
- 47 + 31496119 = 31496166
- 67 + 31496099 = 31496166
- 83 + 31496083 = 31496166
- 109 + 31496057 = 31496166
- 139 + 31496027 = 31496166
- 269 + 31495897 = 31496166
Showing the first eight; more decompositions exist.
