Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555854, here are decompositions:

31 + 555823 = 555854
157 + 555697 = 555854
163 + 555691 = 555854
193 + 555661 = 555854
331 + 555523 = 555854
367 + 555487 = 555854
433 + 555421 = 555854
463 + 555391 = 555854

Showing the first eight; more decompositions exist.
