Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552610, here are decompositions:

7 + 31552603 = 31552610
31 + 31552579 = 31552610
73 + 31552537 = 31552610
181 + 31552429 = 31552610
223 + 31552387 = 31552610
307 + 31552303 = 31552610
373 + 31552237 = 31552610
541 + 31552069 = 31552610

Showing the first eight; more decompositions exist.
