Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592526, here are decompositions:

37 + 31592489 = 31592526
59 + 31592467 = 31592526
73 + 31592453 = 31592526
79 + 31592447 = 31592526
89 + 31592437 = 31592526
103 + 31592423 = 31592526
109 + 31592417 = 31592526
137 + 31592389 = 31592526

Showing the first eight; more decompositions exist.
