Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535454, here are decompositions:

31 + 31535423 = 31535454
37 + 31535417 = 31535454
43 + 31535411 = 31535454
73 + 31535381 = 31535454
113 + 31535341 = 31535454
127 + 31535327 = 31535454
191 + 31535263 = 31535454
227 + 31535227 = 31535454

Showing the first eight; more decompositions exist.
