Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590326, here are decompositions:

13 + 31590313 = 31590326
139 + 31590187 = 31590326
193 + 31590133 = 31590326
349 + 31589977 = 31590326
373 + 31589953 = 31590326
457 + 31589869 = 31590326
499 + 31589827 = 31590326
619 + 31589707 = 31590326

Showing the first eight; more decompositions exist.
