Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592136, here are decompositions:

7 + 31592129 = 31592136
13 + 31592123 = 31592136
83 + 31592053 = 31592136
89 + 31592047 = 31592136
97 + 31592039 = 31592136
137 + 31591999 = 31592136
139 + 31591997 = 31592136
157 + 31591979 = 31592136

Showing the first eight; more decompositions exist.
