Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527384, here are decompositions:
- 41 + 31527343 = 31527384
- 61 + 31527323 = 31527384
- 67 + 31527317 = 31527384
- 73 + 31527311 = 31527384
- 107 + 31527277 = 31527384
- 131 + 31527253 = 31527384
- 137 + 31527247 = 31527384
- 151 + 31527233 = 31527384
Showing the first eight; more decompositions exist.
