Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473122, here are decompositions:

13 + 31473109 = 31473122
61 + 31473061 = 31473122
139 + 31472983 = 31473122
193 + 31472929 = 31473122
271 + 31472851 = 31473122
283 + 31472839 = 31473122
349 + 31472773 = 31473122
643 + 31472479 = 31473122

Showing the first eight; more decompositions exist.
