Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540004, here are decompositions:
- 37 + 31539967 = 31540004
- 73 + 31539931 = 31540004
- 103 + 31539901 = 31540004
- 241 + 31539763 = 31540004
- 277 + 31539727 = 31540004
- 421 + 31539583 = 31540004
- 673 + 31539331 = 31540004
- 733 + 31539271 = 31540004
Showing the first eight; more decompositions exist.
