Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15078, here are decompositions:
- 5 + 15073 = 15078
- 17 + 15061 = 15078
- 47 + 15031 = 15078
- 61 + 15017 = 15078
- 109 + 14969 = 15078
- 127 + 14951 = 15078
- 131 + 14947 = 15078
- 139 + 14939 = 15078
Showing the first eight; more decompositions exist.
