Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552538, here are decompositions:

109 + 31552429 = 31552538
151 + 31552387 = 31552538
229 + 31552309 = 31552538
331 + 31552207 = 31552538
541 + 31551997 = 31552538
601 + 31551937 = 31552538
757 + 31551781 = 31552538
991 + 31551547 = 31552538

Showing the first eight; more decompositions exist.
