Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87018, here are decompositions:
- 5 + 87013 = 87018
- 7 + 87011 = 87018
- 37 + 86981 = 87018
- 59 + 86959 = 87018
- 67 + 86951 = 87018
- 79 + 86939 = 87018
- 89 + 86929 = 87018
- 149 + 86869 = 87018
Showing the first eight; more decompositions exist.
