Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462292, here are decompositions:

3 + 31462289 = 31462292
19 + 31462273 = 31462292
151 + 31462141 = 31462292
223 + 31462069 = 31462292
271 + 31462021 = 31462292
313 + 31461979 = 31462292
331 + 31461961 = 31462292
349 + 31461943 = 31462292

Showing the first eight; more decompositions exist.
