Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455296, here are decompositions:

3 + 31455293 = 31455296
73 + 31455223 = 31455296
157 + 31455139 = 31455296
193 + 31455103 = 31455296
373 + 31454923 = 31455296
487 + 31454809 = 31455296
643 + 31454653 = 31455296
709 + 31454587 = 31455296

Showing the first eight; more decompositions exist.
