Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553452, here are decompositions:

83 + 31553369 = 31553452
101 + 31553351 = 31553452
113 + 31553339 = 31553452
131 + 31553321 = 31553452
173 + 31553279 = 31553452
179 + 31553273 = 31553452
191 + 31553261 = 31553452
233 + 31553219 = 31553452

Showing the first eight; more decompositions exist.
