Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473856, here are decompositions:
- 17 + 31473839 = 31473856
- 47 + 31473809 = 31473856
- 149 + 31473707 = 31473856
- 257 + 31473599 = 31473856
- 263 + 31473593 = 31473856
- 419 + 31473437 = 31473856
- 443 + 31473413 = 31473856
- 593 + 31473263 = 31473856
Showing the first eight; more decompositions exist.
