Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552188, here are decompositions:

61 + 31552127 = 31552188
131 + 31552057 = 31552188
139 + 31552049 = 31552188
191 + 31551997 = 31552188
211 + 31551977 = 31552188
229 + 31551959 = 31552188
251 + 31551937 = 31552188
331 + 31551857 = 31552188

Showing the first eight; more decompositions exist.
