Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532012, here are decompositions:

103 + 31531909 = 31532012
199 + 31531813 = 31532012
373 + 31531639 = 31532012
433 + 31531579 = 31532012
541 + 31531471 = 31532012
613 + 31531399 = 31532012
643 + 31531369 = 31532012
709 + 31531303 = 31532012

Showing the first eight; more decompositions exist.
