Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624184, here are decompositions:

37 + 31624147 = 31624184
43 + 31624141 = 31624184
181 + 31624003 = 31624184
283 + 31623901 = 31624184
367 + 31623817 = 31624184
463 + 31623721 = 31624184
577 + 31623607 = 31624184
661 + 31623523 = 31624184

Showing the first eight; more decompositions exist.
