Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130578, here are decompositions:

31 + 130547 = 130578
47 + 130531 = 130578
61 + 130517 = 130578
89 + 130489 = 130578
101 + 130477 = 130578
109 + 130469 = 130578
131 + 130447 = 130578
139 + 130439 = 130578

Showing the first eight; more decompositions exist.
