Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535570, here are decompositions:

19 + 31535551 = 31535570
67 + 31535503 = 31535570
103 + 31535467 = 31535570
151 + 31535419 = 31535570
193 + 31535377 = 31535570
229 + 31535341 = 31535570
307 + 31535263 = 31535570
337 + 31535233 = 31535570

Showing the first eight; more decompositions exist.
