Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552622, here are decompositions:

19 + 31552603 = 31552622
43 + 31552579 = 31552622
193 + 31552429 = 31552622
229 + 31552393 = 31552622
271 + 31552351 = 31552622
313 + 31552309 = 31552622
643 + 31551979 = 31552622
769 + 31551853 = 31552622

Showing the first eight; more decompositions exist.
