Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15090, here are decompositions:
- 7 + 15083 = 15090
- 13 + 15077 = 15090
- 17 + 15073 = 15090
- 29 + 15061 = 15090
- 37 + 15053 = 15090
- 59 + 15031 = 15090
- 73 + 15017 = 15090
- 107 + 14983 = 15090
Showing the first eight; more decompositions exist.
