Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493526, here are decompositions:

5 + 31493521 = 31493526
7 + 31493519 = 31493526
13 + 31493513 = 31493526
59 + 31493467 = 31493526
79 + 31493447 = 31493526
83 + 31493443 = 31493526
107 + 31493419 = 31493526
149 + 31493377 = 31493526

Showing the first eight; more decompositions exist.
