Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473902, here are decompositions:
- 199 + 31473703 = 31473902
- 373 + 31473529 = 31473902
- 379 + 31473523 = 31473902
- 571 + 31473331 = 31473902
- 619 + 31473283 = 31473902
- 661 + 31473241 = 31473902
- 739 + 31473163 = 31473902
- 751 + 31473151 = 31473902
Showing the first eight; more decompositions exist.
