Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527576, here are decompositions:

7 + 31527569 = 31527576
43 + 31527533 = 31527576
53 + 31527523 = 31527576
79 + 31527497 = 31527576
163 + 31527413 = 31527576
233 + 31527343 = 31527576
383 + 31527193 = 31527576
419 + 31527157 = 31527576

Showing the first eight; more decompositions exist.
