Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478246, here are decompositions:
- 67 + 31478179 = 31478246
- 73 + 31478173 = 31478246
- 157 + 31478089 = 31478246
- 223 + 31478023 = 31478246
- 229 + 31478017 = 31478246
- 277 + 31477969 = 31478246
- 367 + 31477879 = 31478246
- 487 + 31477759 = 31478246
Showing the first eight; more decompositions exist.
