Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527906, here are decompositions:

19 + 31527887 = 31527906
79 + 31527827 = 31527906
89 + 31527817 = 31527906
197 + 31527709 = 31527906
229 + 31527677 = 31527906
337 + 31527569 = 31527906
373 + 31527533 = 31527906
383 + 31527523 = 31527906

Showing the first eight; more decompositions exist.
