Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480416, here are decompositions:
- 43 + 31480373 = 31480416
- 47 + 31480369 = 31480416
- 67 + 31480349 = 31480416
- 127 + 31480289 = 31480416
- 157 + 31480259 = 31480416
- 313 + 31480103 = 31480416
- 337 + 31480079 = 31480416
- 367 + 31480049 = 31480416
Showing the first eight; more decompositions exist.
