Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479682, here are decompositions:
- 11 + 31479671 = 31479682
- 89 + 31479593 = 31479682
- 131 + 31479551 = 31479682
- 191 + 31479491 = 31479682
- 263 + 31479419 = 31479682
- 383 + 31479299 = 31479682
- 431 + 31479251 = 31479682
- 599 + 31479083 = 31479682
Showing the first eight; more decompositions exist.
