Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590250, here are decompositions:
- 89 + 31590161 = 31590250
- 101 + 31590149 = 31590250
- 113 + 31590137 = 31590250
- 179 + 31590071 = 31590250
- 239 + 31590011 = 31590250
- 269 + 31589981 = 31590250
- 359 + 31589891 = 31590250
- 383 + 31589867 = 31590250
Showing the first eight; more decompositions exist.
