Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85700, here are decompositions:
- 31 + 85669 = 85700
- 61 + 85639 = 85700
- 73 + 85627 = 85700
- 79 + 85621 = 85700
- 103 + 85597 = 85700
- 151 + 85549 = 85700
- 271 + 85429 = 85700
- 331 + 85369 = 85700
Showing the first eight; more decompositions exist.
