Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015188, here are decompositions:
- 17 + 1015171 = 1015188
- 29 + 1015159 = 1015188
- 61 + 1015127 = 1015188
- 107 + 1015081 = 1015188
- 127 + 1015061 = 1015188
- 131 + 1015057 = 1015188
- 137 + 1015051 = 1015188
- 149 + 1015039 = 1015188
Showing the first eight; more decompositions exist.
