Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595234, here are decompositions:

61 + 31595173 = 31595234
271 + 31594963 = 31595234
331 + 31594903 = 31595234
367 + 31594867 = 31595234
373 + 31594861 = 31595234
421 + 31594813 = 31595234
487 + 31594747 = 31595234
607 + 31594627 = 31595234

Showing the first eight; more decompositions exist.
