Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1612, here are decompositions:
- 3 + 1609 = 1612
- 5 + 1607 = 1612
- 11 + 1601 = 1612
- 29 + 1583 = 1612
- 41 + 1571 = 1612
- 53 + 1559 = 1612
- 59 + 1553 = 1612
- 89 + 1523 = 1612
Showing the first eight; more decompositions exist.
