Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553204, here are decompositions:

3 + 31553201 = 31553204
43 + 31553161 = 31553204
127 + 31553077 = 31553204
313 + 31552891 = 31553204
373 + 31552831 = 31553204
457 + 31552747 = 31553204
523 + 31552681 = 31553204
601 + 31552603 = 31553204

Showing the first eight; more decompositions exist.
