Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553546, here are decompositions:

19 + 31553527 = 31553546
43 + 31553503 = 31553546
163 + 31553383 = 31553546
313 + 31553233 = 31553546
457 + 31553089 = 31553546
547 + 31552999 = 31553546
853 + 31552693 = 31553546
907 + 31552639 = 31553546

Showing the first eight; more decompositions exist.
