Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552928, here are decompositions:

37 + 31552891 = 31552928
97 + 31552831 = 31552928
181 + 31552747 = 31552928
307 + 31552621 = 31552928
349 + 31552579 = 31552928
439 + 31552489 = 31552928
499 + 31552429 = 31552928
541 + 31552387 = 31552928

Showing the first eight; more decompositions exist.
