Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552292, here are decompositions:

223 + 31552069 = 31552292
313 + 31551979 = 31552292
433 + 31551859 = 31552292
439 + 31551853 = 31552292
571 + 31551721 = 31552292
883 + 31551409 = 31552292
1009 + 31551283 = 31552292
1033 + 31551259 = 31552292

Showing the first eight; more decompositions exist.
