Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42636, here are decompositions:
- 47 + 42589 = 42636
- 59 + 42577 = 42636
- 67 + 42569 = 42636
- 79 + 42557 = 42636
- 103 + 42533 = 42636
- 127 + 42509 = 42636
- 137 + 42499 = 42636
- 149 + 42487 = 42636
Showing the first eight; more decompositions exist.
