Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553234, here are decompositions:

73 + 31553161 = 31553234
157 + 31553077 = 31553234
487 + 31552747 = 31553234
541 + 31552693 = 31553234
613 + 31552621 = 31553234
631 + 31552603 = 31553234
883 + 31552351 = 31553234
997 + 31552237 = 31553234

Showing the first eight; more decompositions exist.
