Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562060, here are decompositions:

3 + 31562057 = 31562060
7 + 31562053 = 31562060
37 + 31562023 = 31562060
43 + 31562017 = 31562060
67 + 31561993 = 31562060
157 + 31561903 = 31562060
307 + 31561753 = 31562060
331 + 31561729 = 31562060

Showing the first eight; more decompositions exist.
