Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579952, here are decompositions:

43 + 31579909 = 31579952
139 + 31579813 = 31579952
211 + 31579741 = 31579952
409 + 31579543 = 31579952
433 + 31579519 = 31579952
499 + 31579453 = 31579952
541 + 31579411 = 31579952
601 + 31579351 = 31579952

Showing the first eight; more decompositions exist.
