Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592344, here are decompositions:

53 + 31592291 = 31592344
131 + 31592213 = 31592344
293 + 31592051 = 31592344
347 + 31591997 = 31592344
431 + 31591913 = 31592344
593 + 31591751 = 31592344
677 + 31591667 = 31592344
743 + 31591601 = 31592344

Showing the first eight; more decompositions exist.
