Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576162, here are decompositions:
- 41 + 31576121 = 31576162
- 71 + 31576091 = 31576162
- 113 + 31576049 = 31576162
- 131 + 31576031 = 31576162
- 239 + 31575923 = 31576162
- 263 + 31575899 = 31576162
- 269 + 31575893 = 31576162
- 281 + 31575881 = 31576162
Showing the first eight; more decompositions exist.
