Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576332, here are decompositions:

43 + 31576289 = 31576332
71 + 31576261 = 31576332
79 + 31576253 = 31576332
101 + 31576231 = 31576332
113 + 31576219 = 31576332
131 + 31576201 = 31576332
163 + 31576169 = 31576332
211 + 31576121 = 31576332

Showing the first eight; more decompositions exist.
