Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492766, here are decompositions:

103 + 31492663 = 31492766
139 + 31492627 = 31492766
163 + 31492603 = 31492766
199 + 31492567 = 31492766
229 + 31492537 = 31492766
313 + 31492453 = 31492766
337 + 31492429 = 31492766
367 + 31492399 = 31492766

Showing the first eight; more decompositions exist.
