Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28902, here are decompositions:
- 23 + 28879 = 28902
- 31 + 28871 = 28902
- 43 + 28859 = 28902
- 59 + 28843 = 28902
- 89 + 28813 = 28902
- 109 + 28793 = 28902
- 113 + 28789 = 28902
- 131 + 28771 = 28902
Showing the first eight; more decompositions exist.
