Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553552, here are decompositions:

193 + 31553359 = 31553552
463 + 31553089 = 31553552
661 + 31552891 = 31553552
673 + 31552879 = 31553552
859 + 31552693 = 31553552
1063 + 31552489 = 31553552
1123 + 31552429 = 31553552
1201 + 31552351 = 31553552

Showing the first eight; more decompositions exist.
