Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532244, here are decompositions:
- 17 + 31532227 = 31532244
- 41 + 31532203 = 31532244
- 103 + 31532141 = 31532244
- 127 + 31532117 = 31532244
- 131 + 31532113 = 31532244
- 173 + 31532071 = 31532244
- 181 + 31532063 = 31532244
- 223 + 31532021 = 31532244
Showing the first eight; more decompositions exist.
