Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87030, here are decompositions:
- 17 + 87013 = 87030
- 19 + 87011 = 87030
- 37 + 86993 = 87030
- 61 + 86969 = 87030
- 71 + 86959 = 87030
- 79 + 86951 = 87030
- 101 + 86929 = 87030
- 103 + 86927 = 87030
Showing the first eight; more decompositions exist.
