Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475132, here are decompositions:
- 43 + 31475089 = 31475132
- 61 + 31475071 = 31475132
- 79 + 31475053 = 31475132
- 103 + 31475029 = 31475132
- 151 + 31474981 = 31475132
- 163 + 31474969 = 31475132
- 331 + 31474801 = 31475132
- 349 + 31474783 = 31475132
Showing the first eight; more decompositions exist.
