Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025142, here are decompositions:
- 5 + 1025137 = 1025142
- 23 + 1025119 = 1025142
- 29 + 1025113 = 1025142
- 31 + 1025111 = 1025142
- 43 + 1025099 = 1025142
- 61 + 1025081 = 1025142
- 103 + 1025039 = 1025142
- 113 + 1025029 = 1025142
Showing the first eight; more decompositions exist.
