Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489004, here are decompositions:

13 + 31488991 = 31489004
73 + 31488931 = 31489004
97 + 31488907 = 31489004
271 + 31488733 = 31489004
373 + 31488631 = 31489004
457 + 31488547 = 31489004
523 + 31488481 = 31489004
541 + 31488463 = 31489004

Showing the first eight; more decompositions exist.
