Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2590, here are decompositions:
- 11 + 2579 = 2590
- 41 + 2549 = 2590
- 47 + 2543 = 2590
- 59 + 2531 = 2590
- 113 + 2477 = 2590
- 131 + 2459 = 2590
- 149 + 2441 = 2590
- 167 + 2423 = 2590
Showing the first eight; more decompositions exist.
