Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455314, here are decompositions:

13 + 31455301 = 31455314
43 + 31455271 = 31455314
193 + 31455121 = 31455314
211 + 31455103 = 31455314
283 + 31455031 = 31455314
433 + 31454881 = 31455314
487 + 31454827 = 31455314
577 + 31454737 = 31455314

Showing the first eight; more decompositions exist.
