Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87412, here are decompositions:
- 5 + 87407 = 87412
- 29 + 87383 = 87412
- 53 + 87359 = 87412
- 89 + 87323 = 87412
- 113 + 87299 = 87412
- 131 + 87281 = 87412
- 191 + 87221 = 87412
- 233 + 87179 = 87412
Showing the first eight; more decompositions exist.
