Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552806, here are decompositions:

59 + 31552747 = 31552806
73 + 31552733 = 31552806
79 + 31552727 = 31552806
97 + 31552709 = 31552806
113 + 31552693 = 31552806
163 + 31552643 = 31552806
167 + 31552639 = 31552806
227 + 31552579 = 31552806

Showing the first eight; more decompositions exist.
