Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552342, here are decompositions:

71 + 31552271 = 31552342
89 + 31552253 = 31552342
113 + 31552229 = 31552342
131 + 31552211 = 31552342
149 + 31552193 = 31552342
293 + 31552049 = 31552342
383 + 31551959 = 31552342
401 + 31551941 = 31552342

Showing the first eight; more decompositions exist.
