Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592546, here are decompositions:

79 + 31592467 = 31592546
109 + 31592437 = 31592546
157 + 31592389 = 31592546
199 + 31592347 = 31592546
373 + 31592173 = 31592546
397 + 31592149 = 31592546
499 + 31592047 = 31592546
547 + 31591999 = 31592546

Showing the first eight; more decompositions exist.
