Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540384, here are decompositions:
- 41 + 31540343 = 31540384
- 167 + 31540217 = 31540384
- 173 + 31540211 = 31540384
- 353 + 31540031 = 31540384
- 521 + 31539863 = 31540384
- 563 + 31539821 = 31540384
- 647 + 31539737 = 31540384
- 677 + 31539707 = 31540384
Showing the first eight; more decompositions exist.
