Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527956, here are decompositions:

43 + 31527913 = 31527956
127 + 31527829 = 31527956
139 + 31527817 = 31527956
373 + 31527583 = 31527956
379 + 31527577 = 31527956
433 + 31527523 = 31527956
457 + 31527499 = 31527956
613 + 31527343 = 31527956

Showing the first eight; more decompositions exist.
