Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540498, here are decompositions:
- 5 + 31540493 = 31540498
- 257 + 31540241 = 31540498
- 281 + 31540217 = 31540498
- 317 + 31540181 = 31540498
- 389 + 31540109 = 31540498
- 467 + 31540031 = 31540498
- 491 + 31540007 = 31540498
- 641 + 31539857 = 31540498
Showing the first eight; more decompositions exist.
