Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606526, here are decompositions:

97 + 31606429 = 31606526
103 + 31606423 = 31606526
139 + 31606387 = 31606526
157 + 31606369 = 31606526
229 + 31606297 = 31606526
439 + 31606087 = 31606526
613 + 31605913 = 31606526
769 + 31605757 = 31606526

Showing the first eight; more decompositions exist.
