Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541048, here are decompositions:
- 31 + 31541017 = 31541048
- 109 + 31540939 = 31541048
- 127 + 31540921 = 31541048
- 181 + 31540867 = 31541048
- 211 + 31540837 = 31541048
- 349 + 31540699 = 31541048
- 379 + 31540669 = 31541048
- 397 + 31540651 = 31541048
Showing the first eight; more decompositions exist.
