Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485742, here are decompositions:

151 + 2147485591 = 2147485742
331 + 2147485411 = 2147485742
373 + 2147485369 = 2147485742
433 + 2147485309 = 2147485742
541 + 2147485201 = 2147485742
601 + 2147485141 = 2147485742
751 + 2147484991 = 2147485742
823 + 2147484919 = 2147485742

Showing the first eight; more decompositions exist.
