Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730142, here are decompositions:

59 + 8730083 = 8730142
293 + 8729849 = 8730142
431 + 8729711 = 8730142
461 + 8729681 = 8730142
521 + 8729621 = 8730142
599 + 8729543 = 8730142
809 + 8729333 = 8730142
1049 + 8729093 = 8730142

Showing the first eight; more decompositions exist.
