Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023890, here are decompositions:

19 + 1023871 = 1023890
139 + 1023751 = 1023890
157 + 1023733 = 1023890
193 + 1023697 = 1023890
313 + 1023577 = 1023890
349 + 1023541 = 1023890
499 + 1023391 = 1023890
523 + 1023367 = 1023890

Showing the first eight; more decompositions exist.
