Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87070, here are decompositions:
- 29 + 87041 = 87070
- 59 + 87011 = 87070
- 89 + 86981 = 87070
- 101 + 86969 = 87070
- 131 + 86939 = 87070
- 227 + 86843 = 87070
- 233 + 86837 = 87070
- 257 + 86813 = 87070
Showing the first eight; more decompositions exist.
