Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87606, here are decompositions:
- 17 + 87589 = 87606
- 19 + 87587 = 87606
- 23 + 87583 = 87606
- 47 + 87559 = 87606
- 53 + 87553 = 87606
- 59 + 87547 = 87606
- 67 + 87539 = 87606
- 83 + 87523 = 87606
Showing the first eight; more decompositions exist.
