Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553152, here are decompositions:

83 + 31553069 = 31553152
89 + 31553063 = 31553152
131 + 31553021 = 31553152
233 + 31552919 = 31553152
269 + 31552883 = 31553152
419 + 31552733 = 31553152
431 + 31552721 = 31553152
443 + 31552709 = 31553152

Showing the first eight; more decompositions exist.
