Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592738, here are decompositions:

61 + 31592677 = 31592738
97 + 31592641 = 31592738
139 + 31592599 = 31592738
181 + 31592557 = 31592738
271 + 31592467 = 31592738
349 + 31592389 = 31592738
577 + 31592161 = 31592738
691 + 31592047 = 31592738

Showing the first eight; more decompositions exist.
