Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003664, here are decompositions:
- 37 + 1003627 = 1003664
- 43 + 1003621 = 1003664
- 157 + 1003507 = 1003664
- 283 + 1003381 = 1003664
- 313 + 1003351 = 1003664
- 373 + 1003291 = 1003664
- 463 + 1003201 = 1003664
- 523 + 1003141 = 1003664
Showing the first eight; more decompositions exist.
