Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472492, here are decompositions:

3 + 31472489 = 31472492
13 + 31472479 = 31472492
43 + 31472449 = 31472492
199 + 31472293 = 31472492
283 + 31472209 = 31472492
313 + 31472179 = 31472492
349 + 31472143 = 31472492
439 + 31472053 = 31472492

Showing the first eight; more decompositions exist.
