Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529154, here are decompositions:

5 + 31529149 = 31529154
47 + 31529107 = 31529154
67 + 31529087 = 31529154
73 + 31529081 = 31529154
101 + 31529053 = 31529154
157 + 31528997 = 31529154
311 + 31528843 = 31529154
313 + 31528841 = 31529154

Showing the first eight; more decompositions exist.
