Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534958, here are decompositions:

79 + 31534879 = 31534958
127 + 31534831 = 31534958
139 + 31534819 = 31534958
157 + 31534801 = 31534958
229 + 31534729 = 31534958
307 + 31534651 = 31534958
397 + 31534561 = 31534958
457 + 31534501 = 31534958

Showing the first eight; more decompositions exist.
