Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552300, here are decompositions:

29 + 31552271 = 31552300
47 + 31552253 = 31552300
71 + 31552229 = 31552300
89 + 31552211 = 31552300
107 + 31552193 = 31552300
173 + 31552127 = 31552300
251 + 31552049 = 31552300
281 + 31552019 = 31552300

Showing the first eight; more decompositions exist.
