Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87148, here are decompositions:
- 29 + 87119 = 87148
- 41 + 87107 = 87148
- 107 + 87041 = 87148
- 137 + 87011 = 87148
- 167 + 86981 = 87148
- 179 + 86969 = 87148
- 197 + 86951 = 87148
- 311 + 86837 = 87148
Showing the first eight; more decompositions exist.
