Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15950, here are decompositions:
- 13 + 15937 = 15950
- 31 + 15919 = 15950
- 37 + 15913 = 15950
- 43 + 15907 = 15950
- 61 + 15889 = 15950
- 73 + 15877 = 15950
- 127 + 15823 = 15950
- 163 + 15787 = 15950
Showing the first eight; more decompositions exist.
