Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616990, here are decompositions:
- 3 + 31616987 = 31616990
- 61 + 31616929 = 31616990
- 73 + 31616917 = 31616990
- 103 + 31616887 = 31616990
- 151 + 31616839 = 31616990
- 241 + 31616749 = 31616990
- 283 + 31616707 = 31616990
- 313 + 31616677 = 31616990
Showing the first eight; more decompositions exist.
