Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87670, here are decompositions:
- 29 + 87641 = 87670
- 41 + 87629 = 87670
- 47 + 87623 = 87670
- 83 + 87587 = 87670
- 113 + 87557 = 87670
- 131 + 87539 = 87670
- 179 + 87491 = 87670
- 197 + 87473 = 87670
Showing the first eight; more decompositions exist.
