Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552524, here are decompositions:

37 + 31552487 = 31552524
103 + 31552421 = 31552524
131 + 31552393 = 31552524
137 + 31552387 = 31552524
173 + 31552351 = 31552524
271 + 31552253 = 31552524
313 + 31552211 = 31552524
317 + 31552207 = 31552524

Showing the first eight; more decompositions exist.
