Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558062, here are decompositions:

5 + 31558057 = 31558062
13 + 31558049 = 31558062
23 + 31558039 = 31558062
43 + 31558019 = 31558062
79 + 31557983 = 31558062
101 + 31557961 = 31558062
103 + 31557959 = 31558062
131 + 31557931 = 31558062

Showing the first eight; more decompositions exist.
