Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87448, here are decompositions:
- 5 + 87443 = 87448
- 41 + 87407 = 87448
- 89 + 87359 = 87448
- 131 + 87317 = 87448
- 149 + 87299 = 87448
- 167 + 87281 = 87448
- 191 + 87257 = 87448
- 197 + 87251 = 87448
Showing the first eight; more decompositions exist.
