Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987552, here are decompositions:
- 11 + 987541 = 987552
- 19 + 987533 = 987552
- 29 + 987523 = 987552
- 43 + 987509 = 987552
- 61 + 987491 = 987552
- 79 + 987473 = 987552
- 89 + 987463 = 987552
- 191 + 987361 = 987552
Showing the first eight; more decompositions exist.
