Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592100, here are decompositions:

47 + 31592053 = 31592100
53 + 31592047 = 31592100
61 + 31592039 = 31592100
101 + 31591999 = 31592100
103 + 31591997 = 31592100
107 + 31591993 = 31592100
191 + 31591909 = 31592100
227 + 31591873 = 31592100

Showing the first eight; more decompositions exist.
