Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552186, here are decompositions:

47 + 31552139 = 31552186
59 + 31552127 = 31552186
137 + 31552049 = 31552186
167 + 31552019 = 31552186
227 + 31551959 = 31552186
359 + 31551827 = 31552186
383 + 31551803 = 31552186
503 + 31551683 = 31552186

Showing the first eight; more decompositions exist.
