Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535092, here are decompositions:

11 + 31535081 = 31535092
59 + 31535033 = 31535092
131 + 31534961 = 31535092
179 + 31534913 = 31535092
293 + 31534799 = 31535092
353 + 31534739 = 31535092
383 + 31534709 = 31535092
401 + 31534691 = 31535092

Showing the first eight; more decompositions exist.
