Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473308, here are decompositions:

67 + 31473241 = 31473308
157 + 31473151 = 31473308
199 + 31473109 = 31473308
241 + 31473067 = 31473308
271 + 31473037 = 31473308
277 + 31473031 = 31473308
379 + 31472929 = 31473308
421 + 31472887 = 31473308

Showing the first eight; more decompositions exist.
