Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527370, here are decompositions:
- 47 + 31527323 = 31527370
- 53 + 31527317 = 31527370
- 59 + 31527311 = 31527370
- 137 + 31527233 = 31527370
- 179 + 31527191 = 31527370
- 197 + 31527173 = 31527370
- 227 + 31527143 = 31527370
- 239 + 31527131 = 31527370
Showing the first eight; more decompositions exist.
