Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590192, here are decompositions:

5 + 31590187 = 31590192
31 + 31590161 = 31590192
43 + 31590149 = 31590192
59 + 31590133 = 31590192
71 + 31590121 = 31590192
103 + 31590089 = 31590192
131 + 31590061 = 31590192
181 + 31590011 = 31590192

Showing the first eight; more decompositions exist.
