Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527450, here are decompositions:
- 37 + 31527413 = 31527450
- 43 + 31527407 = 31527450
- 61 + 31527389 = 31527450
- 107 + 31527343 = 31527450
- 127 + 31527323 = 31527450
- 139 + 31527311 = 31527450
- 173 + 31527277 = 31527450
- 197 + 31527253 = 31527450
Showing the first eight; more decompositions exist.
