Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552126, here are decompositions:

107 + 31552019 = 31552126
149 + 31551977 = 31552126
167 + 31551959 = 31552126
269 + 31551857 = 31552126
443 + 31551683 = 31552126
587 + 31551539 = 31552126
719 + 31551407 = 31552126
773 + 31551353 = 31552126

Showing the first eight; more decompositions exist.
