Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616406, here are decompositions:
- 5 + 31616401 = 31616406
- 13 + 31616393 = 31616406
- 37 + 31616369 = 31616406
- 43 + 31616363 = 31616406
- 47 + 31616359 = 31616406
- 67 + 31616339 = 31616406
- 79 + 31616327 = 31616406
- 109 + 31616297 = 31616406
Showing the first eight; more decompositions exist.
