Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42072, here are decompositions:
- 11 + 42061 = 42072
- 29 + 42043 = 42072
- 53 + 42019 = 42072
- 59 + 42013 = 42072
- 73 + 41999 = 42072
- 89 + 41983 = 42072
- 103 + 41969 = 42072
- 113 + 41959 = 42072
Showing the first eight; more decompositions exist.
