Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529436, here are decompositions:
- 5 + 31529431 = 31529436
- 23 + 31529413 = 31529436
- 83 + 31529353 = 31529436
- 89 + 31529347 = 31529436
- 157 + 31529279 = 31529436
- 163 + 31529273 = 31529436
- 167 + 31529269 = 31529436
- 179 + 31529257 = 31529436
Showing the first eight; more decompositions exist.
