Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552250, here are decompositions:

13 + 31552237 = 31552250
43 + 31552207 = 31552250
181 + 31552069 = 31552250
193 + 31552057 = 31552250
271 + 31551979 = 31552250
313 + 31551937 = 31552250
349 + 31551901 = 31552250
397 + 31551853 = 31552250

Showing the first eight; more decompositions exist.
