Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551934, here are decompositions:

107 + 31551827 = 31551934
131 + 31551803 = 31551934
251 + 31551683 = 31551934
263 + 31551671 = 31551934
347 + 31551587 = 31551934
431 + 31551503 = 31551934
503 + 31551431 = 31551934
521 + 31551413 = 31551934

Showing the first eight; more decompositions exist.
