Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473394, here are decompositions:

131 + 31473263 = 31473394
191 + 31473203 = 31473394
233 + 31473161 = 31473394
311 + 31473083 = 31473394
317 + 31473077 = 31473394
353 + 31473041 = 31473394
431 + 31472963 = 31473394
467 + 31472927 = 31473394

Showing the first eight; more decompositions exist.
