Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535658, here are decompositions:

19 + 31535639 = 31535658
67 + 31535591 = 31535658
107 + 31535551 = 31535658
109 + 31535549 = 31535658
191 + 31535467 = 31535658
229 + 31535429 = 31535658
239 + 31535419 = 31535658
241 + 31535417 = 31535658

Showing the first eight; more decompositions exist.
