Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031238, here are decompositions:
- 7 + 1031231 = 1031238
- 97 + 1031141 = 1031238
- 101 + 1031137 = 1031238
- 157 + 1031081 = 1031238
- 181 + 1031057 = 1031238
- 191 + 1031047 = 1031238
- 251 + 1030987 = 1031238
- 281 + 1030957 = 1031238
Showing the first eight; more decompositions exist.
