Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542284, here are decompositions:

3 + 31542281 = 31542284
181 + 31542103 = 31542284
271 + 31542013 = 31542284
283 + 31542001 = 31542284
307 + 31541977 = 31542284
313 + 31541971 = 31542284
457 + 31541827 = 31542284
523 + 31541761 = 31542284

Showing the first eight; more decompositions exist.
