Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620142, here are decompositions:

31 + 8620111 = 8620142
73 + 8620069 = 8620142
79 + 8620063 = 8620142
199 + 8619943 = 8620142
283 + 8619859 = 8620142
331 + 8619811 = 8620142
541 + 8619601 = 8620142
631 + 8619511 = 8620142

Showing the first eight; more decompositions exist.
