Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473830, here are decompositions:
- 19 + 31473811 = 31473830
- 97 + 31473733 = 31473830
- 127 + 31473703 = 31473830
- 307 + 31473523 = 31473830
- 373 + 31473457 = 31473830
- 433 + 31473397 = 31473830
- 499 + 31473331 = 31473830
- 547 + 31473283 = 31473830
Showing the first eight; more decompositions exist.
