Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544392, here are decompositions:

29 + 31544363 = 31544392
179 + 31544213 = 31544392
239 + 31544153 = 31544392
293 + 31544099 = 31544392
353 + 31544039 = 31544392
359 + 31544033 = 31544392
401 + 31543991 = 31544392
431 + 31543961 = 31544392

Showing the first eight; more decompositions exist.
