Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539164, here are decompositions:
- 103 + 31539061 = 31539164
- 157 + 31539007 = 31539164
- 277 + 31538887 = 31539164
- 337 + 31538827 = 31539164
- 421 + 31538743 = 31539164
- 523 + 31538641 = 31539164
- 541 + 31538623 = 31539164
- 607 + 31538557 = 31539164
Showing the first eight; more decompositions exist.
