Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126636, here are decompositions:
- 5 + 126631 = 126636
- 23 + 126613 = 126636
- 53 + 126583 = 126636
- 89 + 126547 = 126636
- 137 + 126499 = 126636
- 149 + 126487 = 126636
- 163 + 126473 = 126636
- 179 + 126457 = 126636
Showing the first eight; more decompositions exist.
