Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577026, here are decompositions:

17 + 31577009 = 31577026
59 + 31576967 = 31577026
137 + 31576889 = 31577026
317 + 31576709 = 31577026
353 + 31576673 = 31577026
443 + 31576583 = 31577026
587 + 31576439 = 31577026
599 + 31576427 = 31577026

Showing the first eight; more decompositions exist.
