Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596242, here are decompositions:

79 + 31596163 = 31596242
193 + 31596049 = 31596242
313 + 31595929 = 31596242
373 + 31595869 = 31596242
409 + 31595833 = 31596242
523 + 31595719 = 31596242
541 + 31595701 = 31596242
571 + 31595671 = 31596242

Showing the first eight; more decompositions exist.
