Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591852, here are decompositions:

59 + 31591793 = 31591852
101 + 31591751 = 31591852
113 + 31591739 = 31591852
251 + 31591601 = 31591852
353 + 31591499 = 31591852
359 + 31591493 = 31591852
431 + 31591421 = 31591852
443 + 31591409 = 31591852

Showing the first eight; more decompositions exist.
