Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504994, here are decompositions:

7 + 31504987 = 31504994
13 + 31504981 = 31504994
43 + 31504951 = 31504994
193 + 31504801 = 31504994
211 + 31504783 = 31504994
421 + 31504573 = 31504994
541 + 31504453 = 31504994
607 + 31504387 = 31504994

Showing the first eight; more decompositions exist.
