Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492106, here are decompositions:

13 + 31492093 = 31492106
73 + 31492033 = 31492106
193 + 31491913 = 31492106
313 + 31491793 = 31492106
379 + 31491727 = 31492106
409 + 31491697 = 31492106
487 + 31491619 = 31492106
823 + 31491283 = 31492106

Showing the first eight; more decompositions exist.
