Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489052, here are decompositions:

43 + 31489009 = 31489052
61 + 31488991 = 31489052
73 + 31488979 = 31489052
193 + 31488859 = 31489052
421 + 31488631 = 31489052
433 + 31488619 = 31489052
571 + 31488481 = 31489052
619 + 31488433 = 31489052

Showing the first eight; more decompositions exist.
