Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500694, here are decompositions:

3 + 31500691 = 31500694
83 + 31500611 = 31500694
191 + 31500503 = 31500694
311 + 31500383 = 31500694
317 + 31500377 = 31500694
431 + 31500263 = 31500694
587 + 31500107 = 31500694
593 + 31500101 = 31500694

Showing the first eight; more decompositions exist.
