Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489034, here are decompositions:

7 + 31489027 = 31489034
43 + 31488991 = 31489034
103 + 31488931 = 31489034
127 + 31488907 = 31489034
487 + 31488547 = 31489034
541 + 31488493 = 31489034
571 + 31488463 = 31489034
601 + 31488433 = 31489034

Showing the first eight; more decompositions exist.
