Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582598, here are decompositions:
- 67 + 31582531 = 31582598
- 109 + 31582489 = 31582598
- 127 + 31582471 = 31582598
- 181 + 31582417 = 31582598
- 199 + 31582399 = 31582598
- 277 + 31582321 = 31582598
- 331 + 31582267 = 31582598
- 349 + 31582249 = 31582598
Showing the first eight; more decompositions exist.
