Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565432, here are decompositions:

79 + 31565353 = 31565432
109 + 31565323 = 31565432
139 + 31565293 = 31565432
211 + 31565221 = 31565432
313 + 31565119 = 31565432
331 + 31565101 = 31565432
499 + 31564933 = 31565432
541 + 31564891 = 31565432

Showing the first eight; more decompositions exist.
