Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552550, here are decompositions:

13 + 31552537 = 31552550
61 + 31552489 = 31552550
157 + 31552393 = 31552550
163 + 31552387 = 31552550
199 + 31552351 = 31552550
241 + 31552309 = 31552550
313 + 31552237 = 31552550
571 + 31551979 = 31552550

Showing the first eight; more decompositions exist.
