Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153642, here are decompositions:
- 19 + 153623 = 153642
- 31 + 153611 = 153642
- 53 + 153589 = 153642
- 79 + 153563 = 153642
- 109 + 153533 = 153642
- 113 + 153529 = 153642
- 131 + 153511 = 153642
- 173 + 153469 = 153642
Showing the first eight; more decompositions exist.
