Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527844, here are decompositions:

17 + 31527827 = 31527844
167 + 31527677 = 31527844
311 + 31527533 = 31527844
347 + 31527497 = 31527844
353 + 31527491 = 31527844
431 + 31527413 = 31527844
521 + 31527323 = 31527844
653 + 31527191 = 31527844

Showing the first eight; more decompositions exist.
