Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558954, here are decompositions:

71 + 31558883 = 31558954
107 + 31558847 = 31558954
131 + 31558823 = 31558954
281 + 31558673 = 31558954
347 + 31558607 = 31558954
491 + 31558463 = 31558954
521 + 31558433 = 31558954
563 + 31558391 = 31558954

Showing the first eight; more decompositions exist.
