Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467170, here are decompositions:
- 3 + 31467167 = 31467170
- 13 + 31467157 = 31467170
- 37 + 31467133 = 31467170
- 43 + 31467127 = 31467170
- 67 + 31467103 = 31467170
- 103 + 31467067 = 31467170
- 181 + 31466989 = 31467170
- 193 + 31466977 = 31467170
Showing the first eight; more decompositions exist.
