Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611436, here are decompositions:

107 + 31611329 = 31611436
113 + 31611323 = 31611436
137 + 31611299 = 31611436
347 + 31611089 = 31611436
419 + 31611017 = 31611436
569 + 31610867 = 31611436
797 + 31610639 = 31611436
863 + 31610573 = 31611436

Showing the first eight; more decompositions exist.
