Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1772, here are decompositions:
- 13 + 1759 = 1772
- 19 + 1753 = 1772
- 31 + 1741 = 1772
- 73 + 1699 = 1772
- 79 + 1693 = 1772
- 103 + 1669 = 1772
- 109 + 1663 = 1772
- 151 + 1621 = 1772
Showing the first eight; more decompositions exist.
