Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85520, here are decompositions:
- 3 + 85517 = 85520
- 7 + 85513 = 85520
- 67 + 85453 = 85520
- 73 + 85447 = 85520
- 109 + 85411 = 85520
- 139 + 85381 = 85520
- 151 + 85369 = 85520
- 157 + 85363 = 85520
Showing the first eight; more decompositions exist.
