Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42036, here are decompositions:
- 13 + 42023 = 42036
- 17 + 42019 = 42036
- 19 + 42017 = 42036
- 23 + 42013 = 42036
- 37 + 41999 = 42036
- 53 + 41983 = 42036
- 67 + 41969 = 42036
- 79 + 41957 = 42036
Showing the first eight; more decompositions exist.
