Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87454, here are decompositions:
- 11 + 87443 = 87454
- 47 + 87407 = 87454
- 71 + 87383 = 87454
- 131 + 87323 = 87454
- 137 + 87317 = 87454
- 173 + 87281 = 87454
- 197 + 87257 = 87454
- 233 + 87221 = 87454
Showing the first eight; more decompositions exist.
