Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527672, here are decompositions:

13 + 31527659 = 31527672
89 + 31527583 = 31527672
103 + 31527569 = 31527672
131 + 31527541 = 31527672
139 + 31527533 = 31527672
149 + 31527523 = 31527672
151 + 31527521 = 31527672
173 + 31527499 = 31527672

Showing the first eight; more decompositions exist.
