Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505092, here are decompositions:

11 + 31505081 = 31505092
53 + 31505039 = 31505092
89 + 31505003 = 31505092
149 + 31504943 = 31505092
293 + 31504799 = 31505092
389 + 31504703 = 31505092
401 + 31504691 = 31505092
431 + 31504661 = 31505092

Showing the first eight; more decompositions exist.
