Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1654, here are decompositions:
- 17 + 1637 = 1654
- 41 + 1613 = 1654
- 47 + 1607 = 1654
- 53 + 1601 = 1654
- 71 + 1583 = 1654
- 83 + 1571 = 1654
- 101 + 1553 = 1654
- 131 + 1523 = 1654
Showing the first eight; more decompositions exist.
