Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495182, here are decompositions:
- 11 + 31495171 = 31495182
- 29 + 31495153 = 31495182
- 73 + 31495109 = 31495182
- 139 + 31495043 = 31495182
- 163 + 31495019 = 31495182
- 179 + 31495003 = 31495182
- 233 + 31494949 = 31495182
- 239 + 31494943 = 31495182
Showing the first eight; more decompositions exist.
