Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552544, here are decompositions:

7 + 31552537 = 31552544
151 + 31552393 = 31552544
157 + 31552387 = 31552544
193 + 31552351 = 31552544
241 + 31552303 = 31552544
307 + 31552237 = 31552544
337 + 31552207 = 31552544
487 + 31552057 = 31552544

Showing the first eight; more decompositions exist.
