Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74684, here are decompositions:

31 + 74653 = 74684
61 + 74623 = 74684
73 + 74611 = 74684
97 + 74587 = 74684
157 + 74527 = 74684
163 + 74521 = 74684
271 + 74413 = 74684
307 + 74377 = 74684

Showing the first eight; more decompositions exist.
