Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542274, here are decompositions:

41 + 31542233 = 31542274
191 + 31542083 = 31542274
251 + 31542023 = 31542274
263 + 31542011 = 31542274
293 + 31541981 = 31542274
383 + 31541891 = 31542274
641 + 31541633 = 31542274
677 + 31541597 = 31542274

Showing the first eight; more decompositions exist.
