Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492282, here are decompositions:

5 + 31492277 = 31492282
23 + 31492259 = 31492282
191 + 31492091 = 31492282
251 + 31492031 = 31492282
293 + 31491989 = 31492282
389 + 31491893 = 31492282
401 + 31491881 = 31492282
491 + 31491791 = 31492282

Showing the first eight; more decompositions exist.
