Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540268, here are decompositions:
- 7 + 31540261 = 31540268
- 61 + 31540207 = 31540268
- 79 + 31540189 = 31540268
- 337 + 31539931 = 31540268
- 367 + 31539901 = 31540268
- 379 + 31539889 = 31540268
- 541 + 31539727 = 31540268
- 607 + 31539661 = 31540268
Showing the first eight; more decompositions exist.
