Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492592, here are decompositions:

139 + 31492453 = 31492592
163 + 31492429 = 31492592
193 + 31492399 = 31492592
199 + 31492393 = 31492592
223 + 31492369 = 31492592
331 + 31492261 = 31492592
349 + 31492243 = 31492592
379 + 31492213 = 31492592

Showing the first eight; more decompositions exist.
