Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73630, here are decompositions:

17 + 73613 = 73630
23 + 73607 = 73630
41 + 73589 = 73630
47 + 73583 = 73630
59 + 73571 = 73630
83 + 73547 = 73630
101 + 73529 = 73630
107 + 73523 = 73630

Showing the first eight; more decompositions exist.
