Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588356, here are decompositions:
- 5 + 31588351 = 31588356
- 43 + 31588313 = 31588356
- 53 + 31588303 = 31588356
- 89 + 31588267 = 31588356
- 103 + 31588253 = 31588356
- 109 + 31588247 = 31588356
- 157 + 31588199 = 31588356
- 199 + 31588157 = 31588356
Showing the first eight; more decompositions exist.
