Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552494, here are decompositions:

5 + 31552489 = 31552494
7 + 31552487 = 31552494
73 + 31552421 = 31552494
101 + 31552393 = 31552494
107 + 31552387 = 31552494
191 + 31552303 = 31552494
223 + 31552271 = 31552494
241 + 31552253 = 31552494

Showing the first eight; more decompositions exist.
