Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527496, here are decompositions:
- 5 + 31527491 = 31527496
- 83 + 31527413 = 31527496
- 89 + 31527407 = 31527496
- 107 + 31527389 = 31527496
- 173 + 31527323 = 31527496
- 179 + 31527317 = 31527496
- 263 + 31527233 = 31527496
- 347 + 31527149 = 31527496
Showing the first eight; more decompositions exist.
