Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87604, here are decompositions:
- 17 + 87587 = 87604
- 47 + 87557 = 87604
- 113 + 87491 = 87604
- 131 + 87473 = 87604
- 197 + 87407 = 87604
- 281 + 87323 = 87604
- 311 + 87293 = 87604
- 347 + 87257 = 87604
Showing the first eight; more decompositions exist.
