Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87102, here are decompositions:
- 19 + 87083 = 87102
- 31 + 87071 = 87102
- 53 + 87049 = 87102
- 61 + 87041 = 87102
- 89 + 87013 = 87102
- 109 + 86993 = 87102
- 151 + 86951 = 87102
- 163 + 86939 = 87102
Showing the first eight; more decompositions exist.
