Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527700, here are decompositions:
- 3 + 31527697 = 31527700
- 11 + 31527689 = 31527700
- 23 + 31527677 = 31527700
- 41 + 31527659 = 31527700
- 131 + 31527569 = 31527700
- 167 + 31527533 = 31527700
- 179 + 31527521 = 31527700
- 293 + 31527407 = 31527700
Showing the first eight; more decompositions exist.
