Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616838, here are decompositions:
- 89 + 31616749 = 31616838
- 109 + 31616729 = 31616838
- 131 + 31616707 = 31616838
- 151 + 31616687 = 31616838
- 167 + 31616671 = 31616838
- 191 + 31616647 = 31616838
- 269 + 31616569 = 31616838
- 277 + 31616561 = 31616838
Showing the first eight; more decompositions exist.
