Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142002, here are decompositions:
- 11 + 141991 = 142002
- 31 + 141971 = 142002
- 41 + 141961 = 142002
- 43 + 141959 = 142002
- 61 + 141941 = 142002
- 71 + 141931 = 142002
- 131 + 141871 = 142002
- 139 + 141863 = 142002
Showing the first eight; more decompositions exist.
