Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565452, here are decompositions:

29 + 31565423 = 31565452
41 + 31565411 = 31565452
53 + 31565399 = 31565452
101 + 31565351 = 31565452
173 + 31565279 = 31565452
293 + 31565159 = 31565452
383 + 31565069 = 31565452
461 + 31564991 = 31565452

Showing the first eight; more decompositions exist.
