Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528204, here are decompositions:

47 + 31528157 = 31528204
53 + 31528151 = 31528204
83 + 31528121 = 31528204
101 + 31528103 = 31528204
137 + 31528067 = 31528204
167 + 31528037 = 31528204
263 + 31527941 = 31528204
317 + 31527887 = 31528204

Showing the first eight; more decompositions exist.
