Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595444, here are decompositions:

37 + 31595407 = 31595444
61 + 31595383 = 31595444
73 + 31595371 = 31595444
193 + 31595251 = 31595444
271 + 31595173 = 31595444
457 + 31594987 = 31595444
541 + 31594903 = 31595444
571 + 31594873 = 31595444

Showing the first eight; more decompositions exist.
