Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532954, here are decompositions:

31 + 31532923 = 31532954
73 + 31532881 = 31532954
367 + 31532587 = 31532954
373 + 31532581 = 31532954
433 + 31532521 = 31532954
457 + 31532497 = 31532954
601 + 31532353 = 31532954
613 + 31532341 = 31532954

Showing the first eight; more decompositions exist.
