Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158856, here are decompositions:

7 + 158849 = 158856
13 + 158843 = 158856
53 + 158803 = 158856
79 + 158777 = 158856
97 + 158759 = 158856
107 + 158749 = 158856
109 + 158747 = 158856
157 + 158699 = 158856

Showing the first eight; more decompositions exist.
