Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519004, here are decompositions:

43 + 31518961 = 31519004
211 + 31518793 = 31519004
313 + 31518691 = 31519004
331 + 31518673 = 31519004
397 + 31518607 = 31519004
463 + 31518541 = 31519004
523 + 31518481 = 31519004
547 + 31518457 = 31519004

Showing the first eight; more decompositions exist.
