Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87484, here are decompositions:
- 3 + 87481 = 87484
- 11 + 87473 = 87484
- 41 + 87443 = 87484
- 101 + 87383 = 87484
- 167 + 87317 = 87484
- 191 + 87293 = 87484
- 227 + 87257 = 87484
- 233 + 87251 = 87484
Showing the first eight; more decompositions exist.
