Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535414, here are decompositions:

3 + 31535411 = 31535414
37 + 31535377 = 31535414
73 + 31535341 = 31535414
103 + 31535311 = 31535414
151 + 31535263 = 31535414
181 + 31535233 = 31535414
241 + 31535173 = 31535414
271 + 31535143 = 31535414

Showing the first eight; more decompositions exist.
