Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535564, here are decompositions:

13 + 31535551 = 31535564
61 + 31535503 = 31535564
97 + 31535467 = 31535564
223 + 31535341 = 31535564
331 + 31535233 = 31535564
337 + 31535227 = 31535564
421 + 31535143 = 31535564
433 + 31535131 = 31535564

Showing the first eight; more decompositions exist.
