Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91520, here are decompositions:
- 7 + 91513 = 91520
- 61 + 91459 = 91520
- 67 + 91453 = 91520
- 97 + 91423 = 91520
- 109 + 91411 = 91520
- 127 + 91393 = 91520
- 139 + 91381 = 91520
- 151 + 91369 = 91520
Showing the first eight; more decompositions exist.
