Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552532, here are decompositions:

43 + 31552489 = 31552532
103 + 31552429 = 31552532
139 + 31552393 = 31552532
181 + 31552351 = 31552532
223 + 31552309 = 31552532
229 + 31552303 = 31552532
463 + 31552069 = 31552532
499 + 31552033 = 31552532

Showing the first eight; more decompositions exist.
