Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472592, here are decompositions:

5 + 31472587 = 31472592
103 + 31472489 = 31472592
113 + 31472479 = 31472592
233 + 31472359 = 31472592
241 + 31472351 = 31472592
331 + 31472261 = 31472592
353 + 31472239 = 31472592
383 + 31472209 = 31472592

Showing the first eight; more decompositions exist.
