Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462952, here are decompositions:

19 + 31462933 = 31462952
43 + 31462909 = 31462952
181 + 31462771 = 31462952
193 + 31462759 = 31462952
223 + 31462729 = 31462952
229 + 31462723 = 31462952
349 + 31462603 = 31462952
373 + 31462579 = 31462952

Showing the first eight; more decompositions exist.
