Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551194, here are decompositions:

7 + 31551187 = 31551194
43 + 31551151 = 31551194
97 + 31551097 = 31551194
127 + 31551067 = 31551194
271 + 31550923 = 31551194
397 + 31550797 = 31551194
463 + 31550731 = 31551194
523 + 31550671 = 31551194

Showing the first eight; more decompositions exist.
