Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546952, here are decompositions:

43 + 31546909 = 31546952
61 + 31546891 = 31546952
109 + 31546843 = 31546952
139 + 31546813 = 31546952
163 + 31546789 = 31546952
193 + 31546759 = 31546952
211 + 31546741 = 31546952
331 + 31546621 = 31546952

Showing the first eight; more decompositions exist.
