Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550754, here are decompositions:

7 + 31550747 = 31550754
23 + 31550731 = 31550754
31 + 31550723 = 31550754
43 + 31550711 = 31550754
73 + 31550681 = 31550754
83 + 31550671 = 31550754
127 + 31550627 = 31550754
167 + 31550587 = 31550754

Showing the first eight; more decompositions exist.
