Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527564, here are decompositions:

23 + 31527541 = 31527564
31 + 31527533 = 31527564
41 + 31527523 = 31527564
43 + 31527521 = 31527564
67 + 31527497 = 31527564
73 + 31527491 = 31527564
83 + 31527481 = 31527564
151 + 31527413 = 31527564

Showing the first eight; more decompositions exist.
