Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546388, here are decompositions:
- 19 + 31546369 = 31546388
- 37 + 31546351 = 31546388
- 109 + 31546279 = 31546388
- 157 + 31546231 = 31546388
- 229 + 31546159 = 31546388
- 277 + 31546111 = 31546388
- 397 + 31545991 = 31546388
- 487 + 31545901 = 31546388
Showing the first eight; more decompositions exist.
