Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153782, here are decompositions:
- 19 + 153763 = 153782
- 43 + 153739 = 153782
- 193 + 153589 = 153782
- 271 + 153511 = 153782
- 283 + 153499 = 153782
- 313 + 153469 = 153782
- 373 + 153409 = 153782
- 439 + 153343 = 153782
Showing the first eight; more decompositions exist.
