Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987624, here are decompositions:
- 17 + 987607 = 987624
- 31 + 987593 = 987624
- 37 + 987587 = 987624
- 83 + 987541 = 987624
- 101 + 987523 = 987624
- 151 + 987473 = 987624
- 167 + 987457 = 987624
- 191 + 987433 = 987624
Showing the first eight; more decompositions exist.
