Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615592, here are decompositions:

3 + 31615589 = 31615592
103 + 31615489 = 31615592
109 + 31615483 = 31615592
163 + 31615429 = 31615592
193 + 31615399 = 31615592
271 + 31615321 = 31615592
439 + 31615153 = 31615592
733 + 31614859 = 31615592

Showing the first eight; more decompositions exist.
