Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478270, here are decompositions:
- 3 + 31478267 = 31478270
- 97 + 31478173 = 31478270
- 181 + 31478089 = 31478270
- 193 + 31478077 = 31478270
- 277 + 31477993 = 31478270
- 541 + 31477729 = 31478270
- 547 + 31477723 = 31478270
- 601 + 31477669 = 31478270
Showing the first eight; more decompositions exist.
