Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569232, here are decompositions:
- 3 + 31569229 = 31569232
- 173 + 31569059 = 31569232
- 263 + 31568969 = 31569232
- 293 + 31568939 = 31569232
- 311 + 31568921 = 31569232
- 353 + 31568879 = 31569232
- 389 + 31568843 = 31569232
- 509 + 31568723 = 31569232
Showing the first eight; more decompositions exist.
