Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70142, here are decompositions:
- 3 + 70139 = 70142
- 19 + 70123 = 70142
- 31 + 70111 = 70142
- 43 + 70099 = 70142
- 103 + 70039 = 70142
- 139 + 70003 = 70142
- 151 + 69991 = 70142
- 211 + 69931 = 70142
Showing the first eight; more decompositions exist.
