Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616600, here are decompositions:
- 31 + 31616569 = 31616600
- 61 + 31616539 = 31616600
- 79 + 31616521 = 31616600
- 181 + 31616419 = 31616600
- 199 + 31616401 = 31616600
- 241 + 31616359 = 31616600
- 313 + 31616287 = 31616600
- 349 + 31616251 = 31616600
Showing the first eight; more decompositions exist.
