Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534292, here are decompositions:

61 + 31534231 = 31534292
109 + 31534183 = 31534292
151 + 31534141 = 31534292
241 + 31534051 = 31534292
313 + 31533979 = 31534292
373 + 31533919 = 31534292
421 + 31533871 = 31534292
463 + 31533829 = 31534292

Showing the first eight; more decompositions exist.
