Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553792, here are decompositions:

31 + 31553761 = 31553792
73 + 31553719 = 31553792
409 + 31553383 = 31553792
433 + 31553359 = 31553792
631 + 31553161 = 31553792
1153 + 31552639 = 31553792
1171 + 31552621 = 31553792
1213 + 31552579 = 31553792

Showing the first eight; more decompositions exist.
