Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552830, here are decompositions:

13 + 31552817 = 31552830
83 + 31552747 = 31552830
97 + 31552733 = 31552830
103 + 31552727 = 31552830
109 + 31552721 = 31552830
137 + 31552693 = 31552830
149 + 31552681 = 31552830
191 + 31552639 = 31552830

Showing the first eight; more decompositions exist.
