Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1550, here are decompositions:
- 7 + 1543 = 1550
- 19 + 1531 = 1550
- 61 + 1489 = 1550
- 67 + 1483 = 1550
- 79 + 1471 = 1550
- 97 + 1453 = 1550
- 103 + 1447 = 1550
- 127 + 1423 = 1550
Showing the first eight; more decompositions exist.
