Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179520, here are decompositions:
- 23 + 179497 = 179520
- 37 + 179483 = 179520
- 41 + 179479 = 179520
- 59 + 179461 = 179520
- 67 + 179453 = 179520
- 79 + 179441 = 179520
- 83 + 179437 = 179520
- 109 + 179411 = 179520
Showing the first eight; more decompositions exist.
