Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552574, here are decompositions:

37 + 31552537 = 31552574
181 + 31552393 = 31552574
223 + 31552351 = 31552574
271 + 31552303 = 31552574
337 + 31552237 = 31552574
367 + 31552207 = 31552574
541 + 31552033 = 31552574
577 + 31551997 = 31552574

Showing the first eight; more decompositions exist.
