Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492452, here are decompositions:

23 + 31492429 = 31492452
29 + 31492423 = 31492452
31 + 31492421 = 31492452
53 + 31492399 = 31492452
59 + 31492393 = 31492452
83 + 31492369 = 31492452
191 + 31492261 = 31492452
193 + 31492259 = 31492452

Showing the first eight; more decompositions exist.
