Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186504, here are decompositions:
- 23 + 186481 = 186504
- 53 + 186451 = 186504
- 67 + 186437 = 186504
- 107 + 186397 = 186504
- 113 + 186391 = 186504
- 127 + 186377 = 186504
- 193 + 186311 = 186504
- 233 + 186271 = 186504
Showing the first eight; more decompositions exist.
