Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540632, here are decompositions:
- 59 + 31540573 = 31540632
- 103 + 31540529 = 31540632
- 131 + 31540501 = 31540632
- 139 + 31540493 = 31540632
- 191 + 31540441 = 31540632
- 269 + 31540363 = 31540632
- 293 + 31540339 = 31540632
- 419 + 31540213 = 31540632
Showing the first eight; more decompositions exist.
