Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475792, here are decompositions:
- 13 + 31475779 = 31475792
- 43 + 31475749 = 31475792
- 79 + 31475713 = 31475792
- 109 + 31475683 = 31475792
- 181 + 31475611 = 31475792
- 193 + 31475599 = 31475792
- 211 + 31475581 = 31475792
- 349 + 31475443 = 31475792
Showing the first eight; more decompositions exist.
