Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522532, here are decompositions:

3 + 31522529 = 31522532
73 + 31522459 = 31522532
193 + 31522339 = 31522532
313 + 31522219 = 31522532
541 + 31521991 = 31522532
739 + 31521793 = 31522532
859 + 31521673 = 31522532
883 + 31521649 = 31522532

Showing the first eight; more decompositions exist.
