Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473550, here are decompositions:
- 71 + 31473479 = 31473550
- 113 + 31473437 = 31473550
- 137 + 31473413 = 31473550
- 191 + 31473359 = 31473550
- 347 + 31473203 = 31473550
- 359 + 31473191 = 31473550
- 389 + 31473161 = 31473550
- 443 + 31473107 = 31473550
Showing the first eight; more decompositions exist.
