Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537532, here are decompositions:

193 + 31537339 = 31537532
223 + 31537309 = 31537532
331 + 31537201 = 31537532
379 + 31537153 = 31537532
541 + 31536991 = 31537532
661 + 31536871 = 31537532
709 + 31536823 = 31537532
739 + 31536793 = 31537532

Showing the first eight; more decompositions exist.
