Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135624, here are decompositions:
- 7 + 135617 = 135624
- 11 + 135613 = 135624
- 17 + 135607 = 135624
- 23 + 135601 = 135624
- 31 + 135593 = 135624
- 43 + 135581 = 135624
- 53 + 135571 = 135624
- 113 + 135511 = 135624
Showing the first eight; more decompositions exist.
