Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535626, here are decompositions:

197 + 31535429 = 31535626
443 + 31535183 = 31535626
503 + 31535123 = 31535626
569 + 31535057 = 31535626
593 + 31535033 = 31535626
827 + 31534799 = 31535626
839 + 31534787 = 31535626
887 + 31534739 = 31535626

Showing the first eight; more decompositions exist.
