Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616630, here are decompositions:
- 7 + 31616623 = 31616630
- 61 + 31616569 = 31616630
- 109 + 31616521 = 31616630
- 151 + 31616479 = 31616630
- 211 + 31616419 = 31616630
- 229 + 31616401 = 31616630
- 271 + 31616359 = 31616630
- 349 + 31616281 = 31616630
Showing the first eight; more decompositions exist.
