Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449052, here are decompositions:

23 + 31449029 = 31449052
149 + 31448903 = 31449052
311 + 31448741 = 31449052
353 + 31448699 = 31449052
359 + 31448693 = 31449052
431 + 31448621 = 31449052
449 + 31448603 = 31449052
683 + 31448369 = 31449052

Showing the first eight; more decompositions exist.
