Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449060, here are decompositions:

7 + 31449053 = 31449060
17 + 31449043 = 31449060
23 + 31449037 = 31449060
31 + 31449029 = 31449060
43 + 31449017 = 31449060
73 + 31448987 = 31449060
151 + 31448909 = 31449060
157 + 31448903 = 31449060

Showing the first eight; more decompositions exist.
