Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553492, here are decompositions:

109 + 31553383 = 31553492
331 + 31553161 = 31553492
601 + 31552891 = 31553492
613 + 31552879 = 31553492
661 + 31552831 = 31553492
811 + 31552681 = 31553492
853 + 31552639 = 31553492
1063 + 31552429 = 31553492

Showing the first eight; more decompositions exist.
