Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535554, here are decompositions:

3 + 31535551 = 31535554
5 + 31535549 = 31535554
131 + 31535423 = 31535554
137 + 31535417 = 31535554
173 + 31535381 = 31535554
227 + 31535327 = 31535554
233 + 31535321 = 31535554
383 + 31535171 = 31535554

Showing the first eight; more decompositions exist.
