Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449552, here are decompositions:

53 + 31449499 = 31449552
59 + 31449493 = 31449552
73 + 31449479 = 31449552
89 + 31449463 = 31449552
103 + 31449449 = 31449552
131 + 31449421 = 31449552
149 + 31449403 = 31449552
151 + 31449401 = 31449552

Showing the first eight; more decompositions exist.
