Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492952, here are decompositions:

19 + 31492933 = 31492952
31 + 31492921 = 31492952
103 + 31492849 = 31492952
151 + 31492801 = 31492952
181 + 31492771 = 31492952
349 + 31492603 = 31492952
499 + 31492453 = 31492952
523 + 31492429 = 31492952

Showing the first eight; more decompositions exist.
