Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577060, here are decompositions:

3 + 31577057 = 31577060
7 + 31577053 = 31577060
43 + 31577017 = 31577060
103 + 31576957 = 31577060
283 + 31576777 = 31577060
379 + 31576681 = 31577060
421 + 31576639 = 31577060
577 + 31576483 = 31577060

Showing the first eight; more decompositions exist.
