Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472494, here are decompositions:

5 + 31472489 = 31472494
233 + 31472261 = 31472494
293 + 31472201 = 31472494
311 + 31472183 = 31472494
491 + 31472003 = 31472494
503 + 31471991 = 31472494
587 + 31471907 = 31472494
593 + 31471901 = 31472494

Showing the first eight; more decompositions exist.
