Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552700, here are decompositions:

7 + 31552693 = 31552700
19 + 31552681 = 31552700
61 + 31552639 = 31552700
79 + 31552621 = 31552700
97 + 31552603 = 31552700
163 + 31552537 = 31552700
211 + 31552489 = 31552700
271 + 31552429 = 31552700

Showing the first eight; more decompositions exist.
