Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506622, here are decompositions:
- 23 + 31506599 = 31506622
- 53 + 31506569 = 31506622
- 101 + 31506521 = 31506622
- 179 + 31506443 = 31506622
- 263 + 31506359 = 31506622
- 269 + 31506353 = 31506622
- 311 + 31506311 = 31506622
- 359 + 31506263 = 31506622
Showing the first eight; more decompositions exist.
