Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465004, here are decompositions:

13 + 31464991 = 31465004
31 + 31464973 = 31465004
37 + 31464967 = 31465004
223 + 31464781 = 31465004
433 + 31464571 = 31465004
457 + 31464547 = 31465004
523 + 31464481 = 31465004
541 + 31464463 = 31465004

Showing the first eight; more decompositions exist.
