Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507890, here are decompositions:

7 + 507883 = 507890
109 + 507781 = 507890
193 + 507697 = 507890
199 + 507691 = 507890
223 + 507667 = 507890
283 + 507607 = 507890
367 + 507523 = 507890
541 + 507349 = 507890

Showing the first eight; more decompositions exist.
