Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473190, here are decompositions:

3 + 31473187 = 31473190
17 + 31473173 = 31473190
29 + 31473161 = 31473190
83 + 31473107 = 31473190
107 + 31473083 = 31473190
113 + 31473077 = 31473190
149 + 31473041 = 31473190
227 + 31472963 = 31473190

Showing the first eight; more decompositions exist.
