Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142012, here are decompositions:
- 5 + 142007 = 142012
- 41 + 141971 = 142012
- 53 + 141959 = 142012
- 71 + 141941 = 142012
- 149 + 141863 = 142012
- 179 + 141833 = 142012
- 239 + 141773 = 142012
- 251 + 141761 = 142012
Showing the first eight; more decompositions exist.
