Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542446, here are decompositions:

7 + 31542439 = 31542446
73 + 31542373 = 31542446
283 + 31542163 = 31542446
379 + 31542067 = 31542446
409 + 31542037 = 31542446
433 + 31542013 = 31542446
457 + 31541989 = 31542446
547 + 31541899 = 31542446

Showing the first eight; more decompositions exist.
