Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1602, here are decompositions:
- 5 + 1597 = 1602
- 19 + 1583 = 1602
- 23 + 1579 = 1602
- 31 + 1571 = 1602
- 43 + 1559 = 1602
- 53 + 1549 = 1602
- 59 + 1543 = 1602
- 71 + 1531 = 1602
Showing the first eight; more decompositions exist.
