Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576952, here are decompositions:

3 + 31576949 = 31576952
61 + 31576891 = 31576952
109 + 31576843 = 31576952
193 + 31576759 = 31576952
271 + 31576681 = 31576952
313 + 31576639 = 31576952
373 + 31576579 = 31576952
499 + 31576453 = 31576952

Showing the first eight; more decompositions exist.
