Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552874, here are decompositions:

43 + 31552831 = 31552874
127 + 31552747 = 31552874
181 + 31552693 = 31552874
193 + 31552681 = 31552874
271 + 31552603 = 31552874
337 + 31552537 = 31552874
487 + 31552387 = 31552874
523 + 31552351 = 31552874

Showing the first eight; more decompositions exist.
