Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552234, here are decompositions:

5 + 31552229 = 31552234
23 + 31552211 = 31552234
41 + 31552193 = 31552234
107 + 31552127 = 31552234
257 + 31551977 = 31552234
293 + 31551941 = 31552234
431 + 31551803 = 31552234
563 + 31551671 = 31552234

Showing the first eight; more decompositions exist.
