Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038180, here are decompositions:
- 23 + 1038157 = 1038180
- 37 + 1038143 = 1038180
- 53 + 1038127 = 1038180
- 61 + 1038119 = 1038180
- 103 + 1038077 = 1038180
- 107 + 1038073 = 1038180
- 137 + 1038043 = 1038180
- 139 + 1038041 = 1038180
Showing the first eight; more decompositions exist.
