Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623974, here are decompositions:

3 + 31623971 = 31623974
7 + 31623967 = 31623974
43 + 31623931 = 31623974
73 + 31623901 = 31623974
157 + 31623817 = 31623974
271 + 31623703 = 31623974
307 + 31623667 = 31623974
367 + 31623607 = 31623974

Showing the first eight; more decompositions exist.
